(Thanks for your generous help on this issue so far... it's been good to
talk to someone who actually understands this stuff!)
No, if test2 is loaded before test3, we don't expect it to become aware
of test3 being loaded (and in the real world application of this, this
would only occur because the system admin has chosen not to *ever* load
test3). We just want test2 to be able to behave appropriately when test3
is not loaded, and I was hoping to be able to use these existing linker
mechanisms to implement that as opposed to building my own solution.
