When --enable-rpath is used, hardcode the location of the GMP library.

  - SOCKET-MAKE-STREAM now accepts an :ELEMENT-TYPE argument.
 
+ - When --enable-rpath is used in combination with --with-gmp-prefix, then the
+   path of the GMP library is hardcoded into ECL. If the remaining libraries
+   (GC, libffi) are in a similar location this will make ECL work without
+   further flags, and without modifying LD_LIBRARY_PATH or DYLD_LIBRARY_PATH.
