Log Message:
-----------
Move env check at the beginning, better to check before that may break.

Add a comment why we disable ac_cv_func_getpwuid

Add a comment that we need triplet symlink later made

Add how to calculate the max-size

Finally, set ccache max-size, we have some margin with 1.5 GB
