Add quotes around $(CC) when calling check_cc.sh from a Makefile to
pass the value as a single argument to the script even if it has
several words such as "ccache gcc". Conversely, remove quotes in
check_cc.sh when calling $CC to make it a command with potentially
several arguments again.
Fixes: e9886ace222e ("selftests, x86: Rework x86 target architecture detection")
Tested-by: "kernelci.org bot" <bot@xxxxxxxxxxxx>
