How do I link to a shared lib without having that lib's dependencies (the way MS link does)

If you want to give your users a libA.so, which isn't fully functional
at link-time, why not give them a dummy libA.so with the same ABI
for link-time only? I assume your run-time environment is different
from link-time. Of course, they can't use the dummy libA.so for the
the run-time environment.

"-Wl,--no-ignore-needed" is needed so that the libraries after libA.so
will be treated normally.
