8ba6ad703c hurd: Add __pthread_spin_wait and use it 
900778283a ("htl: make pthread_spin_lock really spin") made
pthread_spin_lock really spin and not block, but the current users of
__pthread_spin_lock were assuming that it blocks, i.e. they use it as a
lightweight mutex fitting in just one int.

__pthread_spin_wait provides that support back.

a179673f3d Use --disable-gdbserver in build-many-glibcs.py. 
Now that binutils-gdb has gdbserver at top level, an extra
--disable-gdbserver configure option is needed when configuring
binutils from a git checkout to avoid it also building gdbserver
unnecessarily (although fairly harmlessly).  This patch updates the
options used in build-many-glibcs.py accordingly (although this might
end up not being needed depending on what happens regarding whether
gdbserver gets built for host != target).

Tested with a build-many-glibcs.py compilers build for
aarch64-linux-gnu using binutils-gdb master.

511c91b114 Improve random memcpy benchmark 
Improve the random memcpy benchmark.  Double the number of copies and
increase the memory sizes tested to 512KB.  Add a more detailed
distribution of memcpy alignment and sizes up to 4096 based on SPEC2017
traces.

f6233ab412 Linux: Add io/tst-o_path-locks test

an O_PATH descriptor never releases POSIX advisory locks, so this
commit adds a test case for this behavior.
