I agree, what you need is a 'configure --help' that proposes

  --with-ffcall-prefix[=DIR]  search for ffcall in DIR/include and DIR/lib
  --without-ffcall-prefix     don't search for ffcall in includedir and libdir

I would use an AC_ARG_WITH that produces this help output and then assigns
the value of the with_ffcall_prefix variable to with_avcall_prefix and
with_callback_prefix.
