libvips: new package

[Thomas:
 - Fix variable name: LIBVIPS_CONF_OPTSS -> LIBVIPS_CONF_OPTS
 - Add a lot of --without-<foo> options to make sure we explicitly
   disable optional features that are not handled by the .mk file.
 - Remove the host-swig dependency, which was probably thought of
   being needed by Pieter due to --without-python not being passed
   explicitly.
 - Remove trailing spaces in Config.in.
 - Rename patch to the new naming convention.]

+Subject: [PATCH] Same patch as for systemd in commit
+ http://git.buildroot.net/buildroot/commit/?id=7144f2f04b70553
+
+Fix deactivation of gtk-doc
+
+The tarball contains the Makefile for building documentation with gtk-doc,
+Unfortunately the AM_CONDITIONAL variable is not the correct one, which
+results in an error when running autoreconf.
+
+This patch fixes this issue.
