[petsc-dev] Problem with petsc.pc when configured with --with-single-library=0

[Satish Balay]

Hm --with-single-library=0 is primarily a debugging tool for petsc
developers [to avoid circular dependencies within library components].

So its not really useful for regular usage.

Attaching a patch-fix for this issue - does this work?

patch -Np1 < petsc-pkg-conf-mlib.diff
