A build on IRIX 6.5.30m with cc version, using -n32 -mips4, gives
the following error:

checking floating-point format... configure: WARNING: Unknown floating-point format

It does correctly figure out that the format is big-endian:

checking whether byte ordering is bigendian... (cached) yes

>From a brief check on the mailing list, this is likely to cause problems
with optimizations? Extracting whatever configure was trying to compile and
seeing what it actually turned out (and putting this result into the message
about an "Unknown floating-point format" for any future encountering of this
problem - not something I have time to do...) may be of interest.
