These failures are just like the ELF ones in that the testsuite is fooled
into thinking that the target format is ELF, when the emulation code has
changed the output to something else.  See gas/testsuite/gas/i386/i386.exp

The mips testsuite needs some tidying.  I think most of the failures are
due to wrong padding, different nops, and other fairly simple problems.
