Hi Jed,

This would be really nice.

I'm okay with using a different prefix to determine a different
PETSC_ARCH.  This is one of the core ideas facilitated by HashDist.  I
just wanted to raise it up as another option.

Let's pretend I didn't bring it up :)

The important case to satisfy here is allowing a system package
manager (brew, dpkg, rpm) to have a decent shot at building a
reasonably contained, functional install of PETSc using a --prefix
install.  I do like the ability to compile tutorial examples from a
PETSc install, and this currently works in a --prefix install.  Your
laundry list looks good to me.  Anything else to add Dominique?
