[ Upstream commit b06e15ebd5bfb670f93c7f11a29b8299c1178bc6 ]
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.
