v2 changes:
Rebase and add run-eu-search-tests.sh to EXTRA_DIST.
The elfutils testsuite (including the tests added in this patch) passes
for me on the sourceware buildbots. However the buildbots do not configure
elfutils with --enable-thread-safety. I think we should include this
configure option when the buildbots run elfutils tests.
