Subject: [PATCH] libvirt: do_compile fails 'src/cpu/cpu_map.xml': No such file
 or directory'

In some circumstances where the build tree differs from the source,
libvirt's compile will try to create the symlink for cpu_map.xml before
creating the directory $(abs_builddir)/cpu.

Add a test to create this directory if it hasn't already been created.
