An ongoing project in FreeBSD is the migration to modern, permissively licensed components for the tool chain, which includes moving away from the obsolete binutils components still in the base system. This PR tracks outstanding issues in removing GNU objdump 2.17.50 from the base system.

jmg@, could you update tools/debugscripts/kld_deb.py to use readelf instead of objdump?
gleb@, could you update tools/tools/shlib-compat/shlib-compat.py to use readelf instead of objdump?
jhb@ points out that both kld_deb.py and asf are rendered obsolete by kgdb internally handling FreeBSD kernel module state.

See https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=230288 for an example where sysutils/u-boot-master/Makefile can be made to work for sysutils/u-boot-pine64 with something like: BUILD_DEPENDS+= objdump:devel/binutils to build a correct u-boot-pine64. Based on a WITHOUT_BINUTILS_BOOSTRAP= WITHOUT_BINUTILS= context the build without such a change completed but what was built was wrong.
(In reply to Mark Millard from comment #18) Ignore Comment #18: further testing showed that the problem was intermittent races failing for multi-process builds: MAKE_JOBS_UNSAFE=yes avoids the build problem even without the BUILD_DEPENDS+=objdump:devel/binutils . This was easier to produce on the Pine64+ 2GB environment that I've been using than in the amd64 environment that I've been using.
