There seems to be some code for searching for PETSC_ARCH in the
FindPETSc script:

set (_petsc_arches
    $ENV{PETSC_ARCH}                   # If set, use environment
    variable first
    ${DEBIAN_FLAVORS}  # Debian defaults
    x86_64-unknown-linux-gnu i386-unknown-linux-gnu)

But it doesn't include the following two options that we have in the
old Scons script:

elif os.path.exists(getPetscDir(sconsEnv=sconsEnv)+"/linux-gnu-c-opt"):
        return "linux-gnu-c-opt"
elif os.path.exists(getPetscDir(sconsEnv=sconsEnv)+"/lib/linux-gnu-c-opt"):
        return "linux-gnu-c-opt"

What makes me even more confused is that I don't have any of these
directories in the location where I have installed PETSc (using Dorsal).
