Joseph Myers 4745f4c1ca Correct TEST_COMPAT conditions in totalorder compat tests.
I noticed that the totalorder compat tests mixed TEST_COMPAT
conditions using COMPAT_VER (computed as the first symbol version for
the symbol being tested) and those with a hardcoded GLIBC_2_25.

COMPAT_VER is logically correct here, so this patch changes the tests
to use it.  GLIBC_2_25 is harmless at present (even for _FloatN /
_FloatNx functions added in later glibc versions).  However, if in
future we support _Float16 functions in glibc for any existing
configuration, the test using GLIBC_2_25 would get things wrong
(wrongly think that there are compat versions of totalorderf16 and
totalordermagf16 to test).

(The actual definitions of the compat / versioned symbols for the
totalorder functions make no attempt to deal with the possibility of
libm function support for a new floating-point format, already
supported for other architectures in glibc, being added in some glibc
configuration in future, for which the only vaguely plausible case
would be if some architecture gets _Float128 support it previously
lacked; this is much like functions added after glibc 2.4 not
generally attempting to deal with compat support for long double
changing away from having the same format as double.)

Tested for x86_64, and with build-many-glibcs.py.

	* math/libm-test-compat_totalorder.inc (do_test)
	[TEST_COMPAT (libm, GLIBC_2_25, GLIBC_2_31)]: Change condition to
	[TEST_COMPAT (libm, COMPAT_VER, GLIBC_2_31)].
	* math/libm-test-compat_totalordermag.inc (do_test)
	[TEST_COMPAT (libm, GLIBC_2_25, GLIBC_2_31)]: Likewise.

This directory contains the sources of the GNU C Library.
See the file "version.h" for what release version you have.

The GNU C Library is the standard system C library for all GNU systems,
and is an important part of what makes up a GNU system.  It provides the
system API for all programs written in C and C-compatible languages such
as C++ and Objective C; the runtime facilities of other programming
languages use the C library to access the underlying operating system.

In GNU/Linux systems, the C library works with the Linux kernel to
implement the operating system behavior seen by user applications.
In GNU/Hurd systems, it works with a microkernel and Hurd servers.

The GNU C Library implements much of the POSIX.1 functionality in the
GNU/Hurd system, using configurations i[4567]86-*-gnu.

When working with Linux kernels, this version of the GNU C Library
requires Linux kernel version 3.2 or later.

Also note that the shared version of the libgcc_s library must be
installed for the pthread library to work correctly.

The GNU C Library supports these configurations for using Linux kernels:

	aarch64*-*-linux-gnu
	alpha*-*-linux-gnu
	arm-*-linux-gnueabi
	csky-*-linux-gnuabiv2
	hppa-*-linux-gnu
	i[4567]86-*-linux-gnu
	x86_64-*-linux-gnu	Can build either x86_64 or x32
	ia64-*-linux-gnu
	m68k-*-linux-gnu
	microblaze*-*-linux-gnu
	mips-*-linux-gnu
	mips64-*-linux-gnu
	powerpc-*-linux-gnu	Hardware or software floating point, BE only.
	powerpc64*-*-linux-gnu	Big-endian and little-endian.
	s390-*-linux-gnu
	s390x-*-linux-gnu
	riscv64-*-linux-gnu
	sh[34]-*-linux-gnu
	sparc*-*-linux-gnu

If you are interested in doing a port, please contact the glibc
maintainers; see http://www.gnu.org/software/libc/ for more
information.

See the file INSTALL to find out how to configure, build, and install
the GNU C Library.  You might also consider reading the WWW pages for
the C library at http://www.gnu.org/software/libc/.

The GNU C Library is (almost) completely documented by the Texinfo manual
found in the `manual/' subdirectory.  The manual is still being updated
and contains some known errors and omissions; we regret that we do not
have the resources to work on the manual as much as we would like.  For
corrections to the manual, please file a bug in the `manual' component,
following the bug-reporting instructions below.  Please be sure to check
the manual in the current development sources to see if your problem has
already been corrected.

Please see http://www.gnu.org/software/libc/bugs.html for bug reporting
information.  We are now using the Bugzilla system to track all bug reports.
This web page gives detailed information on how to report bugs properly.

The GNU C Library is free software.  See the file COPYING.LIB for copying
conditions, and LICENSES for notices about a few contributions that require
these additional notices to be distributed.  License copyright years may be
listed using range notation, e.g., 1996-2015, indicating that every year in
