Browse Source 
Add a new config option that allows to specify a list of files
to dump symbols from, and generate a database of symbols, in
stagins/usr/share/google-breakpad/.

This option will enable the use of google breakpad, a
library and tool suite that allows you to distribute an
application to users with compiler-provided debugging
information removed, record crashes in compact "minidump"
files, send them back to your server and produce C and C++
stack traces from these minidumps. Breakpad can also write
minidumps on request for programs that have not crashed.

help
You may specify a space-separated list of binaries and
libraries with full paths relative to $(TARGET_DIR) of which
debug symbols will be dumped for further use with google
breakpad.
A directory structure that can be used by minidump-stackwalk
will be created at:
$(STAGING_DIR)/usr/share/google-breakpad-symbols
