This upgrade is in preparation for adding perf to the Android tree, where
perf needs newer version of elfutils.
This particular snapshot also cleans up the current makefile where only
the host version of libelf.a (needed by elftree). Additional build
targets for libebl.a, libebl_arm.a, and libebl_sh.a are eliminated since
they are not used in the tree at all.
Changes that build other target modules and associated modifications to
work with bionic will be added later.
