Hmm.  I'm certain I did respond to this, but I haven't seen it on the
list...

Anyway, I've now gotten my backtrace to work, but I do need debug
symbols in glibc (I'm using objcopy --add-gnu-debuglink so I don't
have to have a huge libc.so, but can package the symbols separately).
Many thanks for your help, both you and Paul.

My next step is to find out if I can get the unwind info in a separate
section, but that's less critical.
