Matt Madison 988e253f47 goarch.bbclass: fixups for Go mips32 support
* 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.
