It is FBSD_1.2 version that we use for symbols added after HEAD become
CURRENT-9.

I think that you shall change lib/libc/libc_private.h, adding
corresponding definitions for the PJT_CONDATTR_DESTROY/PJT_CONDATTR_INIT
indexes.

Is the patch buildable ?

Interesting question is whether these changes are mergeable to the
stable branch. Possibly yes, if we declare that rtld/libc/libthr shall
be built from the consistent source snapshot.
