Libtool looks for and uses information provided by installed libtool
library files (*.la). In order to be able to find them, it has to know
the default search path of the link editor (see sys_lib_search_path_spec).
Libtool also hardcodes paths to libraries that end up in places not
found by default by the runtime linker; therefore, it also has to know
the default search path of the runtime linker
(sys_lib_dlsearch_path_spec).
Hope that helps.
Cheers,
Ralf
