Since CL 122515, TestAbort is failing on Plan 9.

Change https://golang.org/cl/122464 mentions this issue: runtime: fix TestAbort on Plan 9

@millerresearch

This fix appears to work only on plan9_386, but not on plan9_arm. runtime.abort on 386 is an INT $3 instruction (breakpoint), while on ARM it's "MOVW $0, R0; MOVW (R0),R1" which causes a read fault.

Note that the test failure isn't Plan 9 specific -- it's failing on some linux_arm builders too.

Indeed. Maybe we can add the "sys: trap: fault read" string in the switch?

This may have been fixed by the recently committed https://golang.org/cl/122580.
