Sorry about being unresponsive lately. Trying to correct that (a bit) with
this response.
I haven't upgraded any machine to Fedora 32 yet (I'll do it soon), so I
can't test this myself. But I can make a suggestion without trying it:

It appears that the new <mutex> C++ header file (included by
include/osv/mutex.h, I don't remember why) needs pthread_mutex_clocklock()
to be defined in our pthread header files.
Let's just implement this function. Seeing that our
pthread_mutex_timedlock() is already a stub (nobody ever complained...),
pthread_mutex_clocklock() can also be a stub.
I think this will be easy, and hopefully work.
