To build the regular x86_64 kernel, simply issue

or to build UML:

Running a UML kernel is recommended as it can optimize out any sleep()s or
kernel timers by taking advantage of UML time travel mode, greatly increasing
test efficiency (~3200 tests can be run in under 5 minutes using parallel-vm.py
on a 24 core CPU).
