New Revision: 301471
URL: https://svnweb.freebsd.org/changeset/base/301471
Log:
Use the in-tree sys/elf_common.h to build libelftc.
This fixes build failures on older releases that lack various
definitions such as EM_AARCH64 (which was unfixed before this).
Revert all of the recent compatibility changes that worked around this
problem.
This uses the same method of using the in-tree header as lib/libelf,
lib/libdwarf and usr.bin/readelf.
