Fix all cmake issues related to building for win32 with mxe.
Add support for ./installdeps win32 on Debian/Ubuntu using the mxe apt
repository.
Details:
* default to ENABLE_LTO=OFF on mxe
* set SFML_STATIC_LIBRARIES=TRUE on mxe
* fix the libintl/gettext checking logic
* fix the git dependencies submodule checking logic, and check that it
triggers for mxe
* revert FindSFML.cmake to upstream version, works fine with mxe
* make 'win32' an alias for the 'MinGW-w64-i686' target for
./installdeps, add support for mxe apt repository for Debian/Ubuntu
* change bin2c related cmake code to compile the tool on the host always
even when cross-compiling
* copy src/win32/res/VBA.ico to src/wx/icons since src/win32 has been
removed

Allow selecting target for MSYS2 deps.
For Arch cross builds, do not run yaourt if all deps are already
satisfied.
For Mac Homebrew, only install formulae that do not already have some
version installed, otherwise if the user has a non-default version (such
as --HEAD) the script will error out.
Refactor ./installdeps and add support for mingw-w64 cross builds on
Arch Linux. The latter does not work currently because of a bug in
libuuid in the mingw-w64 crt, and the wxmsw AUR package does not build.
This will hopefully be resolved soon.
Put a copy of FindOpenAL.cmake into our own CMakeScripts/ because
searching for include files with PATH_SUFFIXES of include/ does not work
for cross builds, as it is done in the system version.
Add a more general purpose ./installdeps script to replace
./installdeps-msys2 that handles: Debian Linux, Arch Linux, MSYS2+MinGW,
Mac Homebrew, MacPorts and Fink for Mac. More OSes and distributions
will be added in the future, and the script may be generalized for use
in other projects.
Move Mac package manager setup code into MacPackageManagers.cmake and
greatly improve it. Handles Homebrew, MacPorts and Fink correctly.
Minor tweaks for FindSDL2.cmake: better include dir searching that works
on cygwin, fix flags for MinGW, and quiet pkg-config program errors.
Add MinGW cross-compilation toolchain files, they can be specified on
the cmake command line with:
-DCMAKE_TOOLCHAIN_FILE=../CMakeScripts/Toolchain-cross-MinGW-w64-i686.cmake
or
-DCMAKE_TOOLCHAIN_FILE=../CMakeScripts/Toolchain-cross-MinGW-w64-x86_64.cmake
these work for Cygwin and should work for MinGW on Linux as well.
