Yes, we can certainly support optional use of libraries at configure
time in configure.ac - we do that already with several things
(SDL_Pango, SDL_net, librsvg2, and also libt4k_common) with flags like
"--without-sdlpango".  By default, autotools gives us preprocessor
macros such as "HAVE_SDL_PANGO" to allow C code to behave
appropriately, but we can use whatever macros we want in case
"SCHOOL_MODE" turns out to be not quite identical with "HAVE_XML2".
