If package A is one binary or a set of binaries that always get linked
to a package using it, then it does. It's called a "derivative work".
Yes, this is insane.
The LGPL was specifically written to avoid requiring that code linked
to the library also becomes GPL. That's how it's possible that you
can link non-GPLed programs against GNU libc.

The act of redistributing a program with GPL components ties you to
the GPL.

GPL programs can be redistributed along with other programs that are
not GPL. This was a problem in the early days of Linux distributions
but this problem has since been resolved. Distributing things as source
doesn't tie one to the GPL though. It only becomes a problem when
someone links together GPL and non-GPL things and then distributes the
resulting binary file.
Of course, IANAL, insert standard disclaimer here.
Cheers,
Peter
