go/ssa/interp/external_plan9.go
Alan Donovan cd908f1108 go.tools/ssa/interp: capture stdout/err of target programs and check for "BUG".
The $GOROOT/tests may print "BUG" on failure but do not
necessarily exit zero, so we must capture their output too.

Details:
- make plan9 use unix's valueToBytes function (now in externals.go)
- direct the target's syscall.Write and print/println built-ins to a new utility, write().  This may capture the output into a global variable.
