The MIPS sfp-machine.h has an _FP_CHOOSENAN implementation which
emulates hardware semantics of not preserving signaling NaN payloads
for an operation with two NaN arguments (although that doesn't suffice
to avoid sNaN payload preservation in any case with just one NaN
argument).
However, those are only hardware semantics in the legacy NaN case; in
the NAN2008 case, the architecture documentation says hardware
preserves payloads in such cases. Furthermore, this implementation
assumes legacy NaN semantics, so in the NAN2008 case the
implementation actually has the effect of preserving sNaN payloads but
not preserving qNaN payloads, when both should be preserved.
This patch fixes the code just to copy from the first argument (at the
level of libgcc, it's not meaningful which argument is the first and
which is the second).
Tested for mips64-linux-gnu (soft float, NAN2008) with the glibc math/
tests.

A/ Newer versions of ld64 check the min_version command, and newer versions of
the system assembler inserts this in response to "-mmacosx-version-min=" on
the assembler line. Unless one makes sensible versions, some object is bound
to conflict.
B/ Additionally, there's a difference in behaviour between "as" and "ld" when
presented with xx.yy.zz (ld truncates to xx.yy, as doesn't); net result is
that one needs to pass a truncated version to "as".
So (if the assembler supports minversion commands)
(a) provide a truncated minversion (as asm_macosx_version_min, which is a
driver-only var).
(b) pass this to "as"
(c) Update tests to determine 'HAVE_AS_MMACOSX_VERSION_MIN_OPTION'
(Rainer's patch)
(d) For some reason the testcases are "run" (it's not obvious they need to be,
they are checking compile-time issues)
- anyway, to preserve the status quo, I've left them as exec. However, the
minimum version that can be code-gened for is target-dependent (there are no
released x86 versions before 10.4, for example). To avoid conflicts where
the "as" is assuming some minimum, I've set the testversion to 10.5 (which
is supported by all the archs we have)
(e) We need to ensure that libgcc and crts are generated with a sufficiently
old minversion not to conflict.

The __cpu_indicator_init and __cpu_model symbols are not safe to use
from shared libgcc_s.so from ifunc resolvers, so since gcc-6, only
the definitions from static libgcc.a are used, however the symbols
are kept in libgcc_s as well for backward compatibility (with
appropriate symbol version). On targets without such backward
compatibility concern add cpuinfo to the static library only (this
avoids running the ctor, reduces libgcc_s size and elf abi concerns
about the versioned symbols).
