commit 2d2c271aea8edd4147793ee6eea82b4ebe2143ae
Author: Joseph Myers <joseph@codesourcery.com>
Date:   Fri Nov 20 23:46:23 2015 +0000

    Fix math_private.h multiple include guards.
    
    Various math_private.h headers are guarded by "#ifndef
    _MATH_PRIVATE_H", but never define the macro.  Nothing else defines
    the macro either (the generic math_private.h that they include defines
    a different macro, _MATH_PRIVATE_H_), so those guards are ineffective.
    
    With the recent inclusion of s_sin.c in s_sincos.c, this breaks the
    build for MIPS, since the build of s_sincos.c ends up including
    <math_private.h> twice and the MIPS version defines inline functions
    such as libc_feholdexcept_mips, without a separate fenv_private.h
    header with its own guards such as some architectures have.
    
    This patch fixes all the problem headers to use architecture-specific
    guard macro names, and to define those macros in the headers they
    guard, just as some architectures already do.
    
    Tested for x86 (testsuite, and that installed shared libraries are
    unchanged by the patch), and for mips64 (that it fixes the build).
