We could try to filter out empty directories and non-existent directories at
the end, just before printing to the petscvariables file
The reason we list directories that "the MPI compiler wrappers" already use
is for mixed languages. We cannot be sure that all the linkers (c,c++, fortran)
use each others libraries/directories so we generate a list of all that any of
them use. It would be possible, though I think too fragile and not worth doing
for a couple of unneeded -L's to try to, for each language, remove those that
the compiler for that language already supports internally.
