Subject: Removed all the configure stuff which checked for PETSC_DIR and
 PETSC_ARCH at compile time. This is now done only once at configure time by
 saying 'PETSC=yes [PETSC_DIR=...] [PETSC_ARCH=...]'. You need to update
 Cactus/lib/make/extras/ also.

This closes PR CactusElliptic/1142: EllPETSc solver doesn't link and
PR CactusElliptic/868: EllPETSc needs environment variables.
