[PATCH] libtool: use $PATH_SEPARATOR instead ':'

On OS/2, a path separator is ';' not ':'. So use $PATH_SEPARATOR.

* build-aux/ltmain.in (func_exec_program) [shlibpath_var]:
Replace ':' with $PATH_SEPARATOR.
(func_mode_link) [shlib_search_path]: Likewise.
* m4/libtool.m4 (func_munge_path_list): Likewise.
