For now I pushed a priliminary DESTDIR support to petsc-dev. Currently
it skips sharedlibraries.

Since the conf files in DESTDIR are unuseable [because they point to
INSTALL_DIR] we cannot invoke make targets with PETSC_DIR=DESTDIR

So we'll have to move 'make shared petsc4py' [and other stuff] from
install.py back to 'make all' [and get it working perhaps with
'install_name_tool' on mac]

Th no-DESTDIR mode should continue to work as before [wrt 'make shared
petsc4py' etc..
