stress test

[Ralf Wildenhues]

And here's how I found the remaining subdir problems
and the five year old bug (now also fixed on branch-2-0, BTW):

OK to commit to HEAD?

It's not an exhaustive search, and the "dlopen self" is not really one,
and there might be a couple of bugs in the test.  Whoever wants to
improve it please feel free to do so.

Nota bene: no aclocal coffee break, no burning of CPU cycles in m4 :)

BTW: for branch-1-5, I now get 1 (yes, exactly one!) failure on cygwin
and 2 on MinGW: build-relink2 (both) and mdemo2-make.

Cheers,
Ralf

        * tests/Makefile.am, tests/testsuite.at, tests/stresstest.at:
        New test.  Stresses several combinations of link flags and
        path specifications.  Uses several data types to test linkage
        against symbols in all kinds of (e.g., ELF) sections.
