Remove all backports which are included in this new release. Remove specify-timestamp.patch, looks like this was implemented upstream in: https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=6badd1020f5bebd3f and it seems to work here. Work around binutils linking against the system libiberty instead of the included one. Also binutils now links against libintl, so add gettext as a dependency
