Uprobes support not available:

The above doesn't need uprobes, but it does to a user backtrace. (Or
does a user backtrace require uprobes?)

Hi David,

For the bad-code it doesn't seem to use the uproces, but it gave message about user-space process-tracking facilities not being available:

Running ./systemtap.base/bad-code.exp ...
Executing on host: gcc ./systemtap.base/bad-code.c  -g  -lm   -o bad-code    (timeout = 300)

PASS: bad-code.c compile

Pass 4: compilation failed.  [man error::pass4]

Thanks for adding the fixes for the ones below.  I also added some fixes to address the syscall remappings for the syscall tests.  It looks like the failures might be less than 100 now.

This is pretty good news.  Thanks for putting in so much effort.
