+--without-all disables libraries not needed for ordinary Emacs

 toolkit creates a lot of library dependencies.  So if you want to
 build a small executable with very basic X support, use --without-all
 --with-x-toolkit=no.  For the smallest possible executable without X,
 use --without-all --without-x.  If you want to build with just a few
 features enabled, you can combine --without-all with --with-FEATURE.
