[PATCH] netsurf fixes for GCC-4.4, from netsurf svn.

[Graham Gower <graham.gower@gmail.com>]

Netsurf appears to be statically linked with these libraries, so I
bumped its PR too.

+Stop utterly insane palette entry population.
+Palette entries are always ABGR, regardless of platform endianness.
+This change probably breaks big-endian platforms which, under the old approach,
+had palette entries of the form RGBA (assuming I understood the code correctly).
+
+http://source.netsurf-browser.org/?view=rev&revision=9138
+Fix palette entry population some more. Hopefully, it's completely endian
+agnostic now and still builds with GCC 4.4
