Why do you think the configure script uses the %__cc macro?
Look how %configure is defined (with macros substitued):
rpm --eval '%configure'
If your path is not listed there, it will not be used, as the
configure script internally will only refer to environment
Changing the spec file so that you set
at the beginning of %build might do what you want.
