package/rdma-core: needs NPTL

rdma-core unconditionally uses pthread_spin_lock since its addition in
commit ea47e177f093d7378e8e8e1f50d6f4e3fce0a088 resulting in the
following build failure:

/home/autobuild/autobuild/instance-9/output-1/host/lib/gcc/sh4-buildroot-linux-uclibc/12.2.0/../../../../sh4-buildroot-linux-uclibc/bin/ld: CMakeFiles/hfi1verbs-rdmav34.dir/verbs.c.o: in function `post_recv':
verbs.c:(.text+0xc4): undefined reference to `pthread_spin_lock'

Fixes:
