OB is printing out the v8 mnemonic, and trying to print out the unused
destination register field (bits 25-29) in the instruction, which are
reserved and always must be zero, which matches up to register %g0.

I just tested binutils and it does accept reg + reg and reg + imm
just fine:

	flush	%g1 + 4
	flush	%g1 + %o4
