These checks should probably be conditional on having found blaslapack,
but you don't have a working PETSc this way (it'll fail to link
examples), and as far as I can tell, you're just using configure to
install sowing and not need to hack the makefiles to do the tree
traversal without including $PETSC_ARCH/lib/petsc/conf/petscvariables.
This seems fine and we can eventually move to calling doctext from
Python or doing its job in Python (as part of the last step, moving man
pages to Sphinx).
At a high level, we see here that the cost of make allcite is dominated
by recursive make tree traversal.
