You will get this error if the link-time version of a function symbol
is seen as localentry:0 (ie. not needing a global entry point due to
not needing a valid r2 toc pointer), but the run-time version does.

The most likely thing is that your library was linked against a stub
version of pthread_condattr_destroy.  Making the stub weak will
disable the generation of the optimized localentry:0 plt call code.
So will linking with -Wl,--no-plt-localentry
