Defeat building for mipsarchn32 because there is no corresponding
GOARCH. Neither "mips" nor "mips64" allows go-runtime to compile.
Existing mips32 code assumes the o32 ABI.

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.

Go does not play well with thumb, so ensure that the
toolchain and any packages use arm, not thumb, instructions.

Go only supports shared libraries for some architectures, so
add a variable for use elsewhere that gets a non-null value
only for those architectures.

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.

* This is converging the recipes for go from
meta-virtualization and oe-meta-go
* Add recipes for go 1.7
* go.bbclass is added to ease out writing
recipes for go packages
* go-examples: Add an example, helloworld written in go
This should serve as temlate for writing go recipes
* Disable for musl, at least for now
* Disable for x32/ppc32 which is not supported
