For what it's worth, in GMP we've adopted a scheme of allowing the
user to say ABI=64 (or whatever), or by default choosing the `best'
from among the ABIs that the compiler and host system support.

This is a departure from the existing config tuple, but nicely
separates ISA from ABI.  We did it primarily so the cpu field could be
an exact cpu type like for instance "ultrasparc3", rather than sort of
a combination of cpu and abi like "sparc64".
