petsc.pc isn't being used here. What's probably happening is that Chombo's mk/Make.test has rules (not just variables) and those rules are replacing PETSc rules. Mark Adams (Cc'd) works with Chombo and will know for sure. I'm mildly afraid of Chombo and would use Makefile.user to extract exactly the information you want from PETSc.

Alternatively, include only ${PETSC_DIR}/lib/petsc/conf/variables from PETSc and append the variables as needed to Chombo. The downside of this is that some variables are not namespaced so there could be conflicts depending on Chombo's naming conventions.
