Fix ldbl-128 expm1l spurious underflow (bug 16539).
This patch fixes spurious underflows from ldbl-128 expm1l, as reported in <https://sourceware.org/ml/libc-alpha/2014-06/msg00835.html> and exposed by the tests added for such a bug in the x86 / x86-64 version. The bug and fix are essentially the same, so no separate bug is filed in Bugzilla. Tested for mips64. [BZ #16539] * sysdeps/ieee754/ldbl-128/s_expm1l.c: Include <float.h>. (__expm1l): Return argument unchanged when small but not subnormal.
