have a compile-host version of "nm", not build-host. In order to effect this
we must use autoconf to determine the correct "nm" to use and propagate that
through the makefiles, through llvm-config and finally to GenLibDeps.pl as
an optional argument.
Patch contributed by Anton Korobeynikov. Thanks!

implies -flat and will produce a list of all the symbols for each library
that another library depends on. Run the output through c++filt for
better readability. Also, don't generate a temporary file for storing the
dependent library names. Perl can handle it in a %hash.

some versions of nm don't recognize it (its a gnu option).

any of the fancy graphs or other output. Just produce the flat, makefile
style output on stdout.

format with one library per line, similar to a makefile dependency list.

2. Fix a bug where the lib directory specified also had to be cwd
3. Weight the output so archive->archive edges are shorter
4. Generate two different graphs: one for libraries, one for objects.
5. Adjust the properties of the graphs till it looks nice.

* Make subordinate libraries presented with a vertical list instead of all
  listed on a single line.
