You cannot do this.  Make variables cannot contain makefile fragments.

This is a feature that will be available in the next version of GNU make
(3.80).  There is no set timeframe for its release yet.

The best you can do now is either (a) use ifeq or whatever, or (b) put
the vpath lists in individual files, and include them with:

  include baseline_vps.mk
  include $(THESE)_vps.mk

or whatever.
