Patch to handle those posted:

With this and the SHF_EXCLUDE patch there are only 2 more test failures,
test-nlist and run-varlocs-self.sh, which look like they can be solved by be a
bit more careful what to check (test-nlist relies on symbols being in the
source file declared order, run-varlocs-self.sh relies on ET_REL debuginfo
containing addresses).
