[Crash-utility] [PATCH] Use /usr/bin/nm -D

[Dave Anderson]

Unfortunately on an unstripped version, it drops all ~3000 ' t ' symbols and
only dumps type 'T' symbols.  Probably it should run -Bn first, or recognize
otherwise that it's been stripped, and if it dumps no symbols, [re]try it
with -DBn?

Use "nm -D" to retrieve also the symbols of crash when compiled without -g
(or stripped after compilation and debuginfo extraction).
