Hello,
I'm using the Exherbo distribution where all of our build tools are prefixed (e.g.
x86_64-pc-linux-gnu-cc) and an error is triggered when using the prefix-less tools.While
ccis hardcoded in python's unixccompiler.py, it seems that they expect users of theUnixCCompilerclass to override default executables, which is why I open this PR.If the
CCenvironment variable is defined, use it. If not, use the default one. I only overridecompiler_sobecause it's the only executable that is used.Let me know how you feel about this!
