Avoid PKG_CONFIG_PATH issues. 

Even before this pull request it was required to set PKG_CONFIG_PATH
when cross compiling since pkg-config always searches for native
libraries. This would require to backup an already existing ENV
variable if present, detect the distro specific place the pkgconfig folder is,
and restore the original ENV variable if it was present. Cmake as shown in:
.
http://www.cmake.org/gitweb?p=cmake.git;a=commitdiff;h=3df51470
.
added support for this but requires CMAKE_MINIMUM_REQUIRED_VERSION as 3.1
which is kind of strict since it was released 10 days ago.
.
To avoid the ugliness let just avoid pkg-config when cross compiling. This
means only EGL, SDL2 and GTK3 have to be updated since the rest work w/o
pkg-config.
- EGL is fixed with PR #409
- SDL2 is fixed here and it's trivial.
- GTK3 is non-trivial. For this one use pkg-config for native builds since
  the .pc file is kept up to date automatically. For cross compilation
  use the provided FindGTK3 which I made by using the sed documented
  inside the file and updating the dependencies for GTK3. Since I checked
  each and every single .pc file to make sure they are up to date this
  should have the same behaviour as pkg-config. Prefer the .pc files for
  native builds since it does not need to be manually updated and when
  the native 64bit port gets finished all the cross compile options should
  be removed which is quite easy since most of the code got moved to the
  CMAKE_TOOLCHAIN_FILE.
Note:
Cmake Modules are BSD-3-clause therefore GPL compatible.

#.rst:
# FindGTK3
# --------
#
# FindGTK3.cmake
#
# This module can find the GTK3 widget libraries and several of its
# other optional components like gtkmm, glade, and glademm.
#
# NOTE: If you intend to use version checking, CMake 2.6.2 or later is
#
# ::
#
# required.
#
#
#
# Specify one or more of the following components as you call this find
# module. See example below.
#
# ::
#
# gtk
# gtkmm
# glade
# glademm
#
#
#
# The following variables will be defined for your use
#
# ::
#
# GTK3_FOUND - Were all of your specified components found?
# GTK3_INCLUDE_DIRS - All include directories
# GTK3_LIBRARIES - All libraries
# GTK3_DEFINITIONS - Additional compiler flags
#
#
#
# ::
#
# GTK3_VERSION - The version of GTK3 found (x.y.z)
# GTK3_MAJOR_VERSION - The major version of GTK3
# GTK3_MINOR_VERSION - The minor version of GTK3
# GTK3_PATCH_VERSION - The patch version of GTK3
#
#
#
# Optional variables you can define prior to calling this module:
#
# ::
#
# GTK3_DEBUG - Enables verbose debugging of the module
# GTK3_ADDITIONAL_SUFFIXES - Allows defining additional directories to
# search for include files
#
#
#
# ================= Example Usage:
#
# ::
#
# Call find_package() once, here are some examples to pick from:
#
#
#
# ::
#
# Require GTK 3.6 or later
# find_package(GTK3 3.6 REQUIRED gtk)
#
#
#
# ::
#
# Require GTK 3.10 or later and Glade
# find_package(GTK3 3.10 REQUIRED gtk glade)
#
#
#
# ::
#
# Search for GTK/GTKMM 3.8 or later
# find_package(GTK3 3.8 COMPONENTS gtk gtkmm)
#
#
#
# ::
#
# if(GTK3_FOUND)
# include_directories(${GTK3_INCLUDE_DIRS})
# add_executable(mygui mygui.cc)
# target_link_libraries(mygui ${GTK3_LIBRARIES})
# endif()

# * Detect cairo-gobject library.
# * Update the dependencies of gdk, gtk, pangomm, gdkmm, gtkmm, glade, and
# glademm based on their .pc files. This ammounts to dropping pangoft2
# and gthread from the dependencies (they are still detected) while adding
# cairo-gobject. All of the optional dependencies are required in GTK3.
# Version 1.6 (CMake 3.0)
# * Create targets for each library
# * Do not link libfreetype
# Version 1.5 (CMake 2.8.12)
# * 14236: Detect gthread library
# Detect pangocairo on windows
# Detect pangocairo with gtk module instead of with gtkmm
# * 14259: Use vc100 libraries with MSVC11
# * 14260: Export a GTK2_DEFINITIONS variable to set /vd2 when appropriate
# (i.e. MSVC)
# * Use the optimized/debug syntax for _LIBRARY and _LIBRARIES variables when
# appropriate. A new set of _RELEASE variables was also added.
# * Remove GTK2_SKIP_MARK_AS_ADVANCED option, as now the variables are
# marked as advanced by SelectLibraryConfigurations
# * Detect gmodule, pangoft2 and pangoxft libraries
# Version 1.4 (10/4/2012) (CMake 2.8.10)
# * 12596: Missing paths for FindGTK2 on NetBSD
# * 12049: Fixed detection of GTK include files in the lib folder on
# multiarch systems.
# Version 1.3 (11/9/2010) (CMake 2.8.4)
# * 11429: Add support for detecting GTK2 built with Visual Studio 10.
# Thanks to Vincent Levesque for the patch.
# Version 1.2 (8/30/2010) (CMake 2.8.3)
# * Merge patch for detecting gdk-pixbuf library (split off
# from core GTK in 2.21). Thanks to Vincent Untz for the patch
# and Ricardo Cruz for the heads up.
# Version 1.1 (8/19/2010) (CMake 2.8.3)
# * Add support for detecting GTK2 under macports (thanks to Gary Kramlich)
# Version 1.0 (8/12/2010) (CMake 2.8.3)
# * Add support for detecting new pangommconfig.h header file
# (Thanks to Sune Vuorela & the Debian Project for the patch)
# * Add support for detecting fontconfig.h header
# * Call find_package(Freetype) since it's required
# * Add support for allowing users to add additional library directories
# via the GTK2_ADDITIONAL_SUFFIXES variable (kind of a future-kludge in
# case the GTK developers change versions on any of the directories in the
# future).
# Version 0.8 (1/4/2010)
# * Get module working under MacOSX fink by adding /sw/include, /sw/lib
# to PATHS and the gobject library
# Version 0.7 (3/22/09)
# * Checked into CMake CVS
# * Added versioning support
# * Module now defaults to searching for GTK if COMPONENTS not specified.
# * Added HKCU prior to HKLM registry key and GTKMM specific environment
# variable as per mailing list discussion.
# * Added lib64 to include search path and a few other search paths where GTK
# may be installed on Unix systems.
# * Switched to lowercase CMake commands
# * Prefaced internal variables with _GTK2 to prevent collision
# * Changed internal macros to functions
# * Enhanced documentation
# Version 0.6 (1/8/08)
# Added GTK2_SKIP_MARK_AS_ADVANCED option
# Version 0.5 (12/19/08)
