libtool: respect config.site LT_SYS_LIBRARY_PATH

Browse Source 
Libtool generator code needs to remember the configure time
LT_SYS_LIBRARY_PATH content to allow config.status properly
instantiate default LT_SYS_LIBRARY_PATH libtool run-time value;
Thats because config.status has no idea what the contents of
config.site file is (by default).
* m4/libtool.m4 (_LT_CONFIG): Use the _LT_DECLared
$configure_time_lt_sys_library_path variable as the default for
LT_SYS_DLSEARCH_PATH at run-time.
(_LT_SYS_DYNAMIC_LINKER): Don't change ac_cv_* variable if it is
not necessary. New $configure_time_lt_sys_library_path variable.
* NEWS: Update.

* Noteworthy changes in release ?.? (????-??-??) [?]
** New features:
- LT_SYS_LIBRARY_PATH can be set in config.site, or at configure time
and persists correctly in the generated libtool script.
** Bug fixes:
- Fix a race condition in ltdl dryrun test that would cause spurious
random failures of that test.
- LT_SYS_SEARCHPATH is munged correctly.
- LT_SYS_DLSEARCH_PATH is munged correctly.
* Noteworthy changes in release 2.4.5 (2015-01-19) [stable]
