This adds support for GCC 5.x in LTO mode for IA32, X64, ARM and AARCH64. Due to the fact that the GCC project switched to a new numbering scheme where the first digit is now incremented for every major release, the new toolchain is simply called 'GCC5', and is intended to support all GCC v5.x releases.
Note that this requires the use of an wrapper script, since the GCC toolchain family usually invokes the linker directly, whereas LTO requires GCC to be invoked with the linker arguments decorated with -Wl,xxx prefixes. Since IA32 and X64 enable compiler optimizations (-Os) for both DEBUG and RELEASE builds, LTO support is equally enabled for both targets. On ARM and AARCH64, DEBUG builds are not optimized, and so the LTO optimizations are only enabled for RELEASE.
