You can set foo_LINK to override the link command, but that contains
more than just the linker.  Overriding CC in a way that is more than
just adding to CFLAGS is a bit illogical from a theoretical POV: most
configure tests are done for a specific compiler; if you actually had
two separate compilers with possibly different features, then with
current Autoconf, you'd need two different configure scripts to test
them separately.

Yes, I know, MPI compiler wrappers often are less problematic than
that (except for the abundance of shell quoting errors that they used
to have ...), but I didn't claim theory = practice above.  ;-)
