How about modifying libstdc++-v3/mknumeric_limits so as to mask the
failure if target and CC match certain patterns?  We'd have to pass
target down to mknumeric_limits, but this might even be a good idea:
we could then have pre-built limits files created for each
architecture/OS/multilib, so that cross-builds wouldn't have to
guess.

Short term, we could have mknumeric_limits use the ``default values
for cross compiles'' if the test program fails to compile or to link.
I'm not sure these defaults would be appropriate for AIX64, though.  I
was under the impression those defaults would be correctly computed at
run-time in case of cross compiles, but now I realize that's not the
case.
