If you need that done when running configure checks, then you need to hack CC.

This is not some spurious invention to make your life difficult, Alexandre.
This has always been the fundamental purpose of GNU configuration tuples.
The whole reason to have invented such a convention all those years ago was
so that code just like what we have in glibc could be written safely by
making the assumption that the tuple is a useful identifier.
