Also IRIX seems to have NaN comparison issues.

The issues seem to be much harder to trigger (harder than in VC6 or
Tru64, that is), though: the perl #125298 is the only spot where
the problem has surfaced so far.  Though see also perl #126396,
with long doubles (the #125298 is with plain doubles).

All tests pass now in IRIX in blead with default config,
including the t/op/infnan.t.  With -Duselongdouble nothing
new breaks (known issues with locales and M::BI)
