Per https://github.com/golang/go/wiki/GoArm we need to set GOARM when
cross building for ARMv5, ARMv6 and ARMv7. The current approach of
using TUNE_FEATURES can be error prone, as we can see today when
attempting to build for Cortex-A7 which results in GOARM=''.
Since the value of MACHINEOVERRIDES already consolidates the values of
TUNE_FEATURES into something more consistent we can use the overrides
mechanism to set GOARM, leaving just a little bit of logic in
go_map_arm() to trigger off the arch (basically target vs host)
for the setting of GOARM.

Although RISC-V 64-bit doesn't have official golang support there are
forks that now exist with at least some support and work is ongoing in
the upstream tree. In order to be able to use the goarch class add
support for RISC-V.

While useful on embedded devices for saving disk space, use
of shared runtime in Go is not the usual practice, so disable
it for nativesdk builds. We don't use it for native builds,
either, so this makes the SDK match the native environment
more closely.

These variables are used to control the floating-point instructions emitted by
the go compiler for x86 architectures.
The default is '387' which disables the use of sse/sse2 instructions and is safe
to use on all x86 processors from the i486 onwards.
If TUNE_FEATURES contains a feature set which is known to support sse/sse2
instructions then they are set to 'sse2' to enable the use of these
instructions. This is suitable for most processors from Pentium 4 onwards.
Only the 'core2' and 'corei7' TUNE_FEATURES are defined in the oe-core layer and
are known to support ss2 instructions. Other layers may introduce additional
tunings which support sse2 instructions and for these layers, TARGET_GO386
or go_map_386 should be overridden as needed.

Remove the TUNE_FEATURES references from go_map_arch,
to avoid an unwanted variable dependency. Direct
comparisons of the architecture name are sufficient
for covering what Go currently supports, and using
TUNE_CCARGS_remove adequately handles the conflict
with the cgo-supplied flags for mips.

* Fix the regular expression in the mips test
* Flag as incompatible any mips32 tunes for n32 ABI
or soft-float, as go does not support them.
* Replace mips32r2 tune with mips32r1. Go only supports
mips32r1, which is a strict subset of r2. Adjusting
this tune is not ideal, but is hopefully a temporary
measure until more complete mips32 ISA coverage
arrives upstream.

The previous logic applied a regex to TUNE_FEATURES which could
set the GOARM value to 7 incorrectly, for example when dealing
with an arm1176 core. Simplify to check for the presence of
"armv7" instead. At the same time add a check for "armv6" and
set GOARM to 6 in that case.
