Initially I asked about multiarch because I use different mesa and llvm 
version for 32 bits and 64 bits.
Thus it should be careful of incompatibility.

Then Timothy told me it wouldn't be a problem because everything was 
based on mesa and llvm buildtime.
However switching between 32 bits and 64 bits means that the cache will 
get deleted, because the buildtime will be detected different.

I don't know however if it would clean only the cache for one game, or 
for all games.
