Add build shortcuts.
Fix buildmod build system.

- For the inference rule to compile *.nss files to *.ncs files to
  be successfully processed, all *.ncs files need to be in
  $(OUTPUTDIR).  Projects with a subdirectory under release as an
  $(OUTPUTDIR) need to re-assign the nmake variable first, before
  the master makefile is included.

- Fixed up includes to reference the ACR includes.
