add LTO support, fix libssp link, add -ggdb3 -Og Add support for Link Time Optimization (LTO) on gcc and Clang. Link libssp only when it is on the system, some toolchains like Ubuntu's do not require explicitly linking to libssp. On Win32 try to link it statically. In debug builds with GCC, use -ggdb3 -Og, otherwise use -g . Two new cmake modules were written for this: * FindSSP.cmake -- this is for finding libssp on the system. * UseGCCBinUtilsWrappers.cmake -- this is for using gcc binutils wrappers such as gcc-ar, which is required for gcc LTO to work. These will be distributed separately as well.

add multi-platform build system under `tools/` add some scripts to invoke the build system to build all deps for vbam and vbam itself: - `tools/linux/builder` This builds a mostly static linux binary with a few dynamic deps for xorg and wayland. Using gtk3. This will run on just about any dist. - `tools/osx/builder` Builds a static mac app targetting 10.7. - `tools/win/linux-cross-builder` Builds a static windows binary using the mingw-w64 toolchain. - `tools/win/msys2-builder` Builds a static windows binary in the MSYS2 environment, this may be suffering from a few regressions. Change some cmake code to support the build system, refactor a few things in it.
