script to query PETSc makefile variables?

[Barry Smith]

     The danger is that the PETSc conf/variables makefile defines its  
own variables based on various variables that
are defined in PETSC_ARCH/conf/petscvariables hence the "raw" variable  
values from running config/configure.py may not
always be what you need.

    Yes, this situation has to be fixed. There are too many levels of  
complexity and how can anyone keep track of things, what a mess.
Satish doesn't agree but I think the logic and defines in conf/ 
variables needs to be removed into the config/configure.py system
