Good point.
But i think it should prepend (not append). The shell script wrapper should execute before than ccache.
Otherwise ccache will think the shell script its the compiler and would cache the hash of the shell script instead of hashing the hash of the real compiler.

That its a guideline fedora has for shipping executable scripts in fedora packages.
This is a build script, not part of what gets installed, so its ok.
