For some reason it needs mpif.h explicitly - so its looking for it.
[and adding -Ipath]. But its not looking explicitly for -lpetsc
-lmpiuni etc. [it picks it up from 'make getlinklibs getincludedirs'
from petsc makefiles].

The petscmakefiles changed - so uedge/facets buildsystem need fixes to
work with the new makefile organization [conf/base removed - insted
one has to explicitly use conf/variables and conf/rules]
