I recall that we had this before, but the problem was that "make 
getincludedirs" and  "make getlinklibs" return other things (like 
UMFPACK include files if PETSc has been configured to download and use 
UMFPACK). This caused problems when DOLFIN wanted to use a system 
installed version of UMFPACK.

How would we do this?
