Upgrade elfutils from version 0.97 to 0.138
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. Change-Id: Ifa808ba5ad2881ccb2c0cf44d134931faad801e1
