Work around lgamma(NaN) bug on AIX.

lgamma(NaN) should produce NaN, but on older versions of AIX
it reports an ERANGE error.  While that's been fixed in the latest
version of libm, it'll take awhile for the fix to propagate.  This
workaround is harmless even when the underlying bug does get fixed.
