* aclocal.m4 (grub_PROG_OBJCOPY_ABSOLUTE): take only .text
        section into account, newer toolchains generate unique build ids
        * configure.ac: remove the test for --build-id=none acceptance,
        we want build ids to bre preserved
        * genmk.rb: add -R .note.gnu.build-id to objcopy, so build id
        far from other sections don't cause the raw binary images grow
        size
