Why do they need to be the same?  

The end result of the compiler is the same with ccache, and that is all that matters in this case, meaning you get the same .o with "ccache gcc".  I might have several ccache directories with different sizes on different systems (it takes ~3.4 gigs for a full ccache).

CCACHE_DIR=/tmp/place1 ccache target-gcc ....
CCACHE_DIR=/tmp/place2 ccache target-gcc ....

Regardless of the state of the CCACHE_DIR the .o will be the same.
