I don't really know what *GCC_TEST_OPTIONS is for.
The only thing in configure using it apart from MinGW is Irix,
which frankly is used by ~ no-one.

Emacs autoconf usage is not always best-practice...
It seems to me that both the Irix and MinGW cases should be using
C(PP)FLAGS instead of using GCC_TEST_OPTIONS to modify CC.
