Saw your patch. Problem is that all kernels from 6.14 to 7.4 at least
will require pthread to build the pci endpoint tests. So in the end, I
suggest that we keep your thread dependency.

Not a big deal as 99.99% of people will use a configuration that has
threads enabled. Better that than having random build failures from
time to time in our autobuilders.

Thanks a lot!
