Thomas Petazzoni - Dec. 15, 2012, 5:29 p.m.
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.
