[Bug translator/6477] New: without debuginfo, compiling a process probe script fails silently

Without kernel debuginfo installed, observe the following:

# stap -vvv -e 'probe process("/bin/program_that_does_not_exist").death { }'

Pass 3: translation failed.  Try again with more '-v' (verbose) options.
Running rm -rf /tmp/stapFUASeP

Even if this shouldn't compile, a better error message (or any for that matter)
should be emitted.

(This bug might be related to bug #4311)

Chances are the problem is in the code associated with
collecting symbol table data.  I'm already working on the
area, and will probably end up borrowing code from jkenisto's
dwarfless branch (looking for System.map?) order to do
the deed.
