I'm semi-blindly guessing.

If configure[.ac] finds out that cerf should be used, it adds
LIBCERF_CFLAGS to CFLAGS and LIBCERF_LIBS to LDFLAGS. Those CFLAGS and
LIBS are then used for all the remaining tests.

If that is indeed the case, I believe there are two "bugs":

- gnuplot should figure out that libcerf is not working and not add
those flags at all
- the flags should be added to the globas set of flags at the end, not
at the beginning of the configure script
