Building firefox with debugging support

[Tom McLaughlin]

Hey all, I've been running into problems with firefox hanging while
resolving hosts on my 4.9 machine.  I'm trying to build a debugging
image in order to obtain a stacktrace now for this.  I set DEBUG to yes
using `make config' and have the following options in /etc/make.conf:

CFLAGS= -O -g -pipe
STRIP=

When I run firefox with the -g option to launch it with gdb, gdb says
there are no debugging symbols found.  I know I missed something...  But
where?  Thanks.

Tom
