It is not.  Dozens of different configure tuples don't determine an
ABI.  All of the *-elf, *-coff, etc targets that support multiple ABIs
have a single tuple, and use the compiler to determine which ABI to
target.  Ditto for mips-sgi-irix6.5.

Unfortunately, the idea of having config.sub canonicalize the triplet
based on $CC $CFLAGS won't run: it is config.guess, not config.sub,
that uses the compiler, and even then, it uses CC_FOR_BUILD, not
CFLAGS.

I have another idea that I'm exploring right now.  I'll let you know
when I've got it working.
