However, this fails on Mac OS X, there the binary should be stripped with 'strip -S -x' or some such to keep the global symbols and not with plain 'strip' as done via (Automake) "make install-strip". And there may, of course, be other non-ELF systems with the same problem. IMHO, in such cases libtool should create a wrapper script even when not linking against uninstalled shared libraries, and that warpper script should cause "libtool --mode=install install -s ..." to use the required options for strip.
