Good!  Although -gdwarf-2 _should_ have produced the same effect.

Do you get the same effect with the following command?

   gcc -v -ggdb -g3 hello.c -o hello

In any case, please reconfigure Emacs to use the switches that produce
DWARF 2 debug info, and rebuild Emacs.  The file INSTALL tells how to
do that (search for "CFLAGS").  Note that you will need to use these
switches both in CFLAGS and in LDFLAGS.
