A more helpful error when --without-jemalloc is impossible

When jemalloc is the system allocator (on FreeBSD and NetBSD), trying
to build --without-jemalloc caused an obscure compiler error. Instead,
complain at configure time that --without-jemalloc cannot work. (It
needs to remain an error because it is vexing when configure quietly
ignores an explicit direction.)
