python: build host-python with MAKE1

Browse Source 
Building host-python in parallel sometimes causes "Bus error" during
the installation step on our autobuilders, such as:

  http://autobuild.buildroot.org/results/04bcc907c5e075fe1f39d4f49dcc50ec93708eb4/build-end.log

Extensive testing on one autobuilder has shown that building
host-python with MAKE1 work arounds this strange problem.

# Building host python in parallel sometimes triggers a "Bus error"
# during the execution of "./python setup.py build" in the
