commit 87faac55161d7dd62997fb09e9fcb5890cf6e4c6
Author: Joseph Myers <joseph@codesourcery.com>

    Fix powerpc-nofpu fmaxmagl, fminmagl spurious "invalid" exception (bug
22691).

    For soft-float powerpc, fmaxmagl and fminmagl generate spurious
    "invalid" exceptions for quiet NaN arguments.  This is another case of
    the problems with fabsl inline expansion via comparisons, and so is
    fixed by building those functions with -fno-builtin-fabsl.

    Tested for powerpc (soft-float).

        [BZ #22691]
        * sysdeps/powerpc/nofpu/Makefile [$(subdir) = math]
        (CFLAGS-s_fmaxmagl.c): New variable.
        [$(subdir) = math] (CFLAGS-s_fminmagl.c: Likewise.
