Subject: [PATCH] libtool: stop put /usr/lib{32,64} into RPATH

libtool will insert RPATH if $libdir not in sys_lib_dlsearch_path_spec.
libtool's configure will parse /etc/ld.so.conf for this value.

Without this change the original value is:

- glibc: /lib /usr/lib /usr/lib32 /usr/local/lib
- musl: /lib /usr/lib
