[call for testing] userland debug symbols

[Mark Johnston]

Hello all,

I've been sitting on my changes for a while, but I think they're ready
for testing at this point. They are described here:

http://lists.freebsd.org/pipermail/freebsd-hackers/2010-November/033474.html

Some minor changes from my last patch:

- Changed gdb's default debug-file-directory to /usr/lib/debug.
  I have no problem changing this again, but this seems like a good place.
- Removed hard-coded paths to strip(1) and objcopy(1) from stripbin.sh.
  I explicitly added /usr/bin/ to PATH.

The patch is available here:

www.student.cs.uwaterloo.ca/~m6johnst/patch/symbdir.patch

Would anybody be willing to test this? Of particular interest is
non-i386/amd64 architectures and cross-compiles.

Thanks,
-Mark
