I think the underlying problem for my backtrace and SIG32
problems is that gdb (on the dev-host) is failing to figure out
what library files are mmap'ed.  The only one that shows up in
the output of "info files" is ld-uClibc.so.  If you look at
/proc/<pid>/maps on the target, you can see the other library
files (e.g. libgcc_s, libuClibc, libpthread, etc.) that gdb is
unaware of. There's an example of this shown here:
