We've avoided using gnu make extensions - so there is no usage of 'if'
directives in petsc makefiles. [and we've used include directive as
alternative]

But there is a plan to switch over to gnumake - in which case all of this
code can perhaps be reworked.

And I'm able to reproduce the problem. The issue is not the above line - but
the following [from target 'test']:

>>>>>>
        @if [ "${FC}" != "" ]; then \
          egrep "^#define PETSC_USE_FORTRAN_DATATYPES 1" ${PETSC_DIR}/${PETSC_ARCH}/include/petscconf.h | tee .ftn-dtype.log > /dev/null; \
          if test -s .ftn-dtype.log; then F90TEST="testex5f90t"; else F90TEST="testex5f"; fi; ${RM} .ftn-dtype.log; \
          cd src/snes/examples/tutorials >/dev/null; ${OMAKE} PETSC_ARCH=${PETSC_ARCH}  PETSC_DIR=${PETSC_DIR} $${F90TEST}; \
         fi;

Perhaps a fix is possible. [by somehow figuring out that this is a
prefix build - and flagging an error if PETSC_ARCH is detected - in
'test:' target]
