Subject: [PATCH] python2: use cc_basename to replace CC for checking compiler

When working path contains "clang"/"gcc"/"icc", it might be part of $CC
because of the "--sysroot" parameter. That could cause judgement error
about clang/gcc/icc compilers. e.g.
When "icc" is containded in working path, below errors are reported when
compiling python:
x86_64-wrs-linux-gcc: error: strict: No such file or directory
x86_64-wrs-linux-gcc: error: unrecognized command line option '-fp-model'

Here use cc_basename to replace CC for checking compiler to avoid such
kind of issue.

Upstream-Status: Pending

Patch orignally from Li Zhou, I just rework it to new version
