D'oh. I know what you mean. Don't use
libtool --mode=link $CC -o libfoo.la foo.lo libbar.a
but instead use
libtool --mode=link $CC -o libfoo.la foo.lo -L. -lbar
which is more portable. Well, not really, but at least it does what
you'd expect from libtool: not add libbar to either the archive nor the
shared library, but add its name in the dependency_libs entry of
libfoo.la, so that programs linked against libfoo.la will pick it up.
Sure this may be regarded as a libtool limitation. Just as putting a
/path/to/shlib.so right on the command line. Both is bad: on some
systems, the latter will hardcode the path into the output -- not really
what you'd expect in any case.
Cheers,
