We have a helper function in glibc (_dl_find_object) that replaces all
the previous object traversal logic and caching in libgcc, so it's no
longer an issue with current gcc and glibc. Unfortunately that means
that the generic dl_iterate_phdr code will be fixed by adding its own
locking.
Thanks,
Florian
