After this change FreeBSD's libthr fails to link with many duplicate
symbol errors, e.g.:

/tank/emaste/src/llvm/build-dim/bin/ld.lld: error: duplicate symbol
'pthread_atfork' in version script
/tank/emaste/src/llvm/build-dim/bin/ld.lld: error: duplicate symbol
'pthread_attr_destroy' in version script
/tank/emaste/src/llvm/build-dim/bin/ld.lld: error: duplicate symbol
'pthread_attr_getdetachstate' in version script

I've put a cpio at https://people.freebsd.org/~emaste/lld/libthr.cpio.xz
