Subject: [PATCH V2 1/2] selftests: x86: add validity check and allow field splitting

Add check to test if CC has a string. CC can have multiple sub-strings
like "ccache gcc". Erorr pops up if it is treated as single string and
double quotes are used around it. This can be fixed by removing the
quotes and not treating CC as a single string.

Fixes: e9886ace222e ("selftests, x86: Rework x86 target architecture detection")
