23     # where lib is named directly with $(get_libdir) if possible.

59     # in some cases when linking dynamic, the .a in /usr/lib is used
60     # instead of the .so in /lib due to gcc/libtool tweaking ld's
61     # library search path. This cause many builds to fail.
62     # See bug #4411 for more info.
63     #
64     # To use, simply call:
65     #
66     # gen_usr_ldscript libfoo.so
67     #
68     # Note that you should in general use the unversioned name of
69     # the library, as ldconfig should usually update it correctly
70     # to point to the latest version of the library present.
