python-native: Fix a compiler finding issue

The CC variable sometimes add option information after compiler name, but python can't get the real compiler name if those information added.
Fix this issue by dropping the option information when finding compiler name.

+# The CC variable,sometimes like:"x86_64-poky-linux-gcc   -m64 --sysroot=/${TMPDIR}/sysroots/qemux86-64", contains option information. 
+# This will lead to wrong compiler name "qemux86-64" rather than "x86_64-poky-linux-gcc" when python finding the compiler name.
