The default linear package is PETSc, assuming ./configure manages to
detect your PETSc configuration. Were your PETSC_DIR and PETSC_ARCH
flags set correctly when you ran configure? If libMesh's configure
script discovers that $PETSC_ARCH is defined and the file
$PETSC_DIR/include/petsc.h exists, it should choose to use PETSc.
