That's "wrong thing" as in having

Actually, it's not Darwin-local. It uses __MACH__, which is also defined
for Hurd. And because sfp-machine.h gets

One of the committed changes breaks the build of libgcc for 32-bit x86
configurations without SSE2 enabled by default:
In file included from
/scratch/jmyers/glibc-bot/src/gcc/libgcc/soft-fp/extendhfsf2.c:31:
/scratch/jmyers/glibc-bot/src/gcc/libgcc/soft-fp/half.h:62:1: error: unable to
emulate
Patch below fixes bootstrap,
OK if it passes testing on x86_64 darwin/linux?
(if !OK .. then suggestions welcome)
thanks

I'm going to check in the first 3 patches which are already approved.
Update hf soft-fp from glibc.
[i386] Enable _Float16 type for TARGET_SSE2 and above.
[i386] libgcc: Enable hfmode soft-sf/df/xf/tf extensions and
truncations.

Update from v2:
1. Support -fexcess-precision=16 which will enable
FLT_EVAL_METHOD_PROMOTE_TO_FLOAT16 when backend supports _Float16.
2. Update ix86_get_excess_precision, so -fexcess-precision=standard
should not do anything different from -fexcess-precision=fast
regarding _Float16.
3. Avoiding
