[PATCH] patsubstfor LOCALVERSION and -fno-omit-frame-pointer

(** Sorry, I'm resending this mail. I had written the subject in the
Reply-To field. **)

Hello, I'm attaching two patches for the top Makefile.

The first patch modifies LOCALVERSION definition such taht it uses
patsubst instead of subst to remove surrounding double quotes from
CONFIG_LOCALVERSION. This helps syntax-highlighting editors.

The second patch addes -fno-omit-frame-pointer to CFLAGS when
CONFIG_FRAME_POINTER is set. My gcc (gcc-3.3.4 Debian 1:3.3.4-11)
automatically turns on -fomit-frame-pointer when -O2 is specified and
thus breaks CONFIG_FRAME_POINTER option. I'm not sure if other
versions of gcc wouldn't choke with -fno-omit-frame-pointer. My 2.95
(2.95.4) seems to be OK though.
