bug#54633: [PATCH] * configure.ac: Fix --without-gif for W32, NS, Haiku, and PGTK.

[Randy Taylor]

When I build Emacs I specify "--without-gif".

When using PGTK:
  - With the original code and specifying "--without-gif", here is what 
configure gives me: Does Emacs use a gif library?                           yes 
-lgif
  - With the patch and specifying "--without-gif", I get this (as expected): 
Does Emacs use a gif library?                           no
  - With the patch, if I remove "--without-gif" or specify "--with-gif=yes", I 
get this (as expected): Does Emacs use a gif library?                           
yes -lgif

When using X11:
  - With the original code and specifying "--without-gif", here is what 
configure gives me (as expected): Does Emacs use a gif library?                 
          no
  - With the original code and removing "--without-gif" or specifying 
"--with-gif="yes", here is what configure gives me (as expected): Does Emacs 
use a gif library?                           yes -lgif

The check in the code for "--without-gif" only applies to X11, but not the 
other systems.
This patch fixes it to apply for all the systems in that check, in the same 
fashion as the SVG check (see line 2660 in configure.ac).
