commit 4fede0bc497021e28fde0635c1fa0da010cc2733
Author: Gary V. Vaughan <address@hidden>
Date:   Fri Dec 12 11:35:28 2014 +0000

    libtool: take care not to double-apply LT_SYS_LIBRARY_PATH.
    
    * m4/libtool.m4 (_LT_CONFIG_SAVE_COMMANDS): Copy configure-time
    LT_SYS_LIBRARY_PATH settings as default, but allow run-time
    override.
    (_LT_SYS_DYNAMIC_LINKER): Save the unmunged
    sys_lib_dlsearch_path_spec value, and use it for _LT_DECL,
    but then munge it with LT_SYS_LIBRARY_PATH for use in ltdl.m4
    macros, such as LT_SYS_DLSEARCH_PATH.
