glibc-2.21 -- x86: ERANGE failures for exp10*, exp2* ,pow* and tgamma.

[Carlos O'Donell]

Joseph,

The 32-bit x86 builds fail test-float for me with ERANGE failures
in exp10*, exp2*, pow* and tgamma tests.

You can see the test-float.out output here under x86 (32-bit, Linux):
https://sourceware.org/glibc/wiki/Release/2.21

Before I investigate I wanted to know if you had any thoughts about
the source of this failure?

Cheers,
Carlos.
