You need the special strip program. One could think of avoiding
running strip by storing the blah.debug files in the gdb.base source
directory, but then the executable built at the time you run the tests
wouldn't be stripped as gdb expects it.  One other way would be to
maybe store the strip program somewhere in the gdb source, but I don't
think this elfutils/strip is FSF.

I know that Jim was able to run the testsuite but I think he relied on
having the proper strip installed on the system.
