Hello,

The attached patch modifies the gdb_mbuild.sh so that it post-processes 
the output from each target's `maint print architecture' command.

The post processing does two things:

- (using addr2line) replaces <0xNNNN> with the name of the corresponding 
function / variable

- strips off any leading path info included in any file name paths

Doing this makes the task of comparing the `maint print architecture' 
output from separate gdb_mbuild.sh runs easier - functions and file 
names are identical.

thoughts?
