2d2c271aea 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).

	[!ARM_MATH_PRIVATE_H].

0747f81811 Fix libm feraiseexcept namespace (bug 17723). 
Various C90 and UNIX98 libm functions call feraiseexcept, which is not
in those standards.  This causes linknamespace test failures - except
on x86 / x86_64, where feraiseexcept is inline (for the relevant
constant arguments) in bits/fenv.h.

This patch fixes this by making those functions call __feraiseexcept
instead.  All changes are applied to all architectures rather than
considering the possibility that some might not be needed in some
cases (e.g. x86) as it seems most maintainable to keep architectures
consistent.

Where __feraiseexcept does not exist, it is added, with feraiseexcept
made a weak alias; where it is a strong alias, it is made weak.
libm_hidden_def / libm_hidden_proto are used with __feraiseexcept
(this might in some cases improve code generation for existing calls
to __feraiseexcept in some code on some architectures).  Where there
are dummy feraiseexcept macros (on architectures without
floating-point exceptions support, to avoid compile errors from
references to undefined FE_* macros), corresponding dummy
__feraiseexcept macros are added.  And on x86, to ensure
__feraiseexcept calls still get inlined, the inline function in
bits/fenv.h is refactored so that most of it can be reused in an
inline __feraiseexcept in a separate include/bits/fenv.h.

Calls are changed in C90/UNIX98 functions, but generally not in
functions missing from those standards.  They are also changed in
libc_fe* functions (on the basis that those might be used in any libm
function), and in feupdateenv (on the same basis - may be used, via
default libc_*, in any libm function - of course feupdateenv will need
changing to __feupdateenv in a subsequent patch to make that fully
namespace-clean).

No __feraiseexcept is added corresponding to the feraiseexcept in
powerpc bits/fenvinline.h, because that macro definition is
conditional on !defined __NO_MATH_INLINES, and glibc libm is built
with -D__NO_MATH_INLINES, so changing internal calls to use
__feraiseexcept should make no difference.

Tested for x86_64 (testsuite; the only change in disassembly of
installed shared libraries is a slight code reordering in clog10, of
no apparent significance).  Also tested for MIPS, where (in the
configuration tested) it eliminates math.h linknamespace failures for
n32 and n64 (some for o32 remain because of other issues).

0025b4cc84 tile: add no-op fe*() routines for libc internal use 
These avoid having tile generate real calls to the no-op
functions, which then causes linknamespace test failures.

It might make sense to factor all of these out into a common
header that can be shared by tile, microblaze, etc., but for
now just fix the test failures.

4372980f58 Move tilegx, tilepro, and linux-generic from ports to libc. 
I've moved the TILE-Gx and TILEPro ports to the main sysdeps hierarchy,
along with the linux-generic ports infrastructure.  Beyond the README
update, the move was just

    git mv ports/sysdeps/tile sysdeps/tile
    git mv ports/sysdeps/unix/sysv/linux/tile \
      sysdeps/unix/sysv/linux/tile
    git mv ports/sysdeps/unix/sysv/linux/generic \
      sysdeps/unix/sysv/linux/generic

I updated the relevant ChangeLogs along the lines of the ARM move
in commit c6bfe5c4d7 and tested the 64-bit tilegx build to confirm that
there were no changes in "objdump -dr" output in the shared objects.
