No hacks are required here. If you link in the library on the command
line, then the code directly uses it. If you don't link the
library on the command line, then a dependency is not required.

Or put another way, if you specify that proga should be linked against
libb (only), then proga should not be linked against libc, even if
libb depends on libc, as this will occur at run-time.

If the programmer forgets to directly link in an important library,
and by pure coincidence it gets linked indirectly at run time, then
that is the programmers fault, and libtool shouldn't go out of its way
to try and resolve/break the issue.
