Likely problem in stap_compile.exp

Hi,

Seems there's problem in testsuite/lib/stap_compile.exp when
matching the output with expected results since commit
a4433a9da1f21c6536266531308ba231e5efae81.

This is one piece of systemtap.base/marker.exp test log.

running stap -v -p4 -e "probe kernel.mark(\"kvm_trace_entryexit\") { }"

FAIL: K_MARKER02_compile failed, but got no error messages
PASS: K_MARKER02 compilation succeeded

It's a little odd to say FAIL and PASS together. In fact,
it works fine on FC11.
