[petsc-dev] So CFLAGS no longer works!!!! Major crisis

Well we wanted to always have  CFLAGS initialized by configure [to ignore stuff from env].

So now - if we are setting in makefile - it has to be set after this default is set - i.e after the line:

include ${PETSC_DIR}/lib/petsc/conf/variables

Or do:

make CFLAGS=garbase ex1

There might be a different bug lurking here..
