[OE-core] [PATCH 1/2] goarch: Remove target specific dependencies

[Khem Raj]

goarch is used in all classes of recipes ranging from native to target,
therefore its best to contain the variables and not spill over into
recipe classes where they can adversely affect shared state reuse e.g.
go-native currently gets TUNE_FEATURES into dependency chain of
referenced variables which means go-native gets rebuilt when we change
from qemuarm to qemux86 machine types since TUNE_FEATURES is defined
with DEFAULTTUNE which would change as machines are switched

These variables are specific to arm/mips/x86 so marking them with
appropriate overrides for native recipes will be right thing here

Chose 'hardfloat' for mips which is default too, 7 for arm and sse2 for x86
somehow go-native bootstrap compiler (1.4) still needs them so feed
commonly used values or defaults.

Fixes
ERROR: go-native different signature for task do_configure.sigdata between qemux86copy and qemuarm
...
List of dependencies for variable TUNE_FEATURES changed from '{'DEFAULTTUNE', 'TUNE_FEATURES_tune-core2-32'}' to '{'DEFAULTTUNE', 'TUNE_FEATURES_tune-armv7vethf-neon'}'
changed items: {'TUNE_FEATURES_tune-core2-32', 'TUNE_FEATURES_tune-armv7vethf-neon'}
