    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.
