Use --without-sound to disable sound support.
Use --disable-features if you want to build small executable with
the minimal dependencies from an external libraries, at the cost
of disabling most of the features which are enabled by default.
Using --disable-features is equivalent to --without-sound --without-dbus
--without-libotf --without-selinux --without-xft --without-gsettings
--without-gnutls --without-rsvg --without-xml2 --without-gconf
--without-imagemagick --without-m17n-flt --without-jpeg --without-tiff
--without-gif --without-png --without-gpm. Note that --disable-features
leaves X support enabled, and using GTK2 or GTK3 toolkit creates a lot
of library dependencies. So if you want to build small executable with
the very basic X support, use --disable-features --with-x-toolkit=no.
For the smallest possible executable without X, use --disable-features
--without-x.
Use --with-wide-int to implement Emacs values with the type 'long long',
even on hosts where a narrower type would do. With this option, on a
typical 32-bit host, Emacs integers have 62 bits instead of 30.
