[PATCH] Disable some functions unused in stage 1.5

[Pavel Roskin]

Hello!

"make check" fails in the latest CVS version.  ufs2_stage1_5 is longer
than 7168 bytes (it's 7348 bytes for me).  I'm using Debian unstable with
gcc 3.3.3.  I believe new versions of gcc optimize primarily for speed
regardless of flags.

I used the unrefglobals script to find unreferenced functions:
http://savannah.gnu.org/cgi-bin/viewcvs/mc/mc/maint/unrefglobals.pl?rev=HEAD&content-type=text/plain

The functions disabled in this patch are not everything that can be done
to reduce the size of the stage 1.5 binaries, but their elimination is
enough to make ufs2_stage1_5 7124 bytes long, slightly below the limit.

ChangeLog:

        * stage2/char_io.c (safe_parse_maxint): Disable for stage 1.5.
        (grub_tolower): Disable for stage 1.5 except fat_stage1_5.
        (grub_memcmp): Disable for stage 1.5 except iso9660_stage1_5.
