autoconf: Allow static library builds
Allow the user to specify that they want static libraries through the --{enable,disable}-{static,shared} switches like libtool. The mesa build only allows for one at a time, so static will be chosen if someone has passed --enable-static or --disable-shared. This also allows the mklib options to be set at build time. This allows -static to be set for mklib, but any platform specific settings are allowed by setting MKLIB_OPTIONS for configure. Handling of the program libraries through the APP_LIB_DEPS variable is pretty ugly, but it seems to work.
