i've seen this issue, too. i did a complete buildworld/installword using gcc
as compiler and after that everything worked fine again.

so clang seems to be causing the problem. simply back out any clang entries in
src.conf and buildworld/installworld should fix your issue.
please also see the thread "issue with clang and CPUTYPE native" on
freebsd-toolchain, which seems to also be caused by the rtld issue.

cheers.
