Subject: [PATCH] cmd/dist,cmd/go: define assembly macros, handle GOARM value
with soft/hardfloat
CL 525637 added GOARM_x assembly macros based on GOARM value. But
it did not define the macro in cmd/dist, so the macro is not set
during bootstrapping. This CL defines them.
With CL 514907, cfg.GOARM can also take a soft/hardfloat suffix,
like "7,hardfloat". Handle that case.
For #65601.
