ARM port of testsuite and general testsuite fixes

That's because of another bug in the expect script.  (I've fixed a
dozen of these bugs now so I'm rather disappointed with myself that
I missed this one until now.)

Patched attached.  With the patch, systemtap.base/cache.exp passes
all 18 tests just fine now.  I had to bump the timeout up too.
I added a "timeout" condition to be complete.


As an aside, any reason that spaces are escaped in these regular
expressions?  I didn't change it in this patch, but why are the
regular expressions written like this:
  -re {^Pass\ [1234]:[^\r]*\ in\ [^\r]*\ ms\.\r\n} {exp_continue}
  -re {^Pass\ [34]: using cached [^\r\n]+\r\n} {incr cached 1; exp_continue}

And not like this?:
  -re {^Pass [1234]:[^\r]* in [^\r]* ms\.\r\n} {exp_continue}
  -re {^Pass [34]: using cached [^\r\n]+\r\n}  {incr cached 1; exp_continue}
