as error output not -j64 safe

[Matthew Fortune]

Hi Alan/Mike,

This patch has broken a lot of expected output in the gas testsuite.
Are individual ports expected to deal with the fallout or has this been
done already but awaiting commit? MIPS has 133 failures with this patch
applied.

Regards,
Matthew
