python/python3: 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.

eg: if build under /yocto/builds/xicc/,  bitbake python,  $CC will contains
xicc, will make $CC match *icc, but actuall xicc just folder name.

When "*icc" is matched, below errors are reported when
compiling python/python3:
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.

+
+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 python3:
+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
