Re: '0514 libstdc++ fails building powerpc/limitsMEMBERS.cc onrs6000-ibm-aix4.2.0.0

[rbrown64 at csc dot com dot au]

The use of mknumeric_limits needs  more thought for multilibbed
environments
- on AIX. Rainer's recent change makes it clear that the prior build
problem reported
was caused by mknumeric_limits failing.
Maybe if in a multilibed environment, gen-num-limits should fall back to
using the `native'
build of mknumeric_limits if the multisubdir version fails.

        * mknumeric_limits: Stop if gen-num-limits dies.
