It shouldn't be changed by Dorsal anywhere along the way. There is
some code in FindPETSc.cmake that tries to figure out PETSC_DIR. Look
for this passage:

  # Try to figure out PETSC_ARCH if not set
  if (PETSC_DIR AND NOT PETSC_ARCH)

You can start by printing out the value of PETSC_ARCH prior to this
and see if it looks ok:

  message("DEBUG PETSC_ARCH = ${PETSC_ARCH}")
