elfutils: remove unused variables to fix compilation with GCC 4.6
Unused variables trigger a warning in GCC 4.6 which are caught by -Werror as used in the elfutils makefiles and therefore the build fails. This patch adds some consolidated fixes from upstream to remove the unused variables, they will no longer be required as of elfutils 0.152 Signed-off-by: Joshua Lock <josh@linux.intel.com>

+Remove unused variables from the code to prevent -Werror causing a build
+failure on hosts with GCC 4.6.
+
+These changes are all upstream so should not be required once we've updated
+to elfutils 0.152 or later. Therefore this patch consolidates several
+changes from elfutils upstream by Roland McGrath into a single file so that
+it's easier to remove later once we upgrade.
+Links to upstream gitweb of the consolidated commits follow:
