    Fix alpha sqrt fegetenv namespace (bug 20768).

    On alpha, sqrt (a C90 function) brings in references to fegetenv
    (C99), resulting in linknamespace test failures:

    [initial] __sqrt -> [libm.a(w_sqrt.o)] __ieee754_sqrt ->
    [libm.a(e_sqrt.o)] __feholdexcept -> [libm.a(feholdexcpt.o)] fegetenv

    This patch fixes this by making __feholdexcept call __fegetenv instead
    of fegetenv.

    Tested for Alpha (compilation only).

        [BZ #20768]
        * sysdeps/alpha/fpu/feholdexcpt.c (__feholdexcept): Call
        __fegetenv instead of fegetenv.
