fenv-exceptions-trapping: Avoid test failure on NetBSD/sparc

[Bruno Haible]

On NetBSD 8.0/sparc I see a test failure of test-fenv-except-trapping-2.sh.
This patch avoids the failure.

        fenv-exceptions-trapping: Avoid test failure on NetBSD/sparc.
        * tests/test-fenv-except-trapping-2.c (main): Skip the 'long double'
        tests also on NetBSD/sparc.
