Re: [x265] MSYS2/MinGW - ccache hook probably not well supported

[Mario *LigH* Rohkrämer]

Solved by borrowing the toolchain files from the CMake call in MABS.

The configuration step for x265 seems to fail requesting its feature set 
correctly, I even doubt it is aware of its presence at all, and its 
hooking into compiler calls might have unwanted side effects.


An example from the configuration in an MSYS2-64/MinGW32 compilation:

[x265] MSYS2/MinGW - ccache hook probably not well supported
