allow building of individual files or sub-directories
PATCH 1/1 allow building of individual files or sub-directories
For the purpose of quick compile testing of (namely smaller) changes, provide a means to build individual pieces underneath the xen dir (could equally be applied to tools, and the top level Makefile could also be made aware of this logic to make things even more consistent). At once, add a way to only pre-process files in case some of the more complicated macros need change and hence inspection of the results.
