[Bug ld/4284] New: Linker "relax" option results in bad subroutine calls

[sbell at dataplay dot com]

I am compiling and linking C for an ATmega2560. When I use the default options,
the resulting code works fine.  When I try to remove unused trampoline entries
by placing -W,--relax in the ld options, the resulting code seems to have bad
subroutine calls.

Not all subroutine calls are bad, nor are all "bad" call targets always called
with a bad address.

Since the code image is around 120KBytes, this is a complex problem and my code
would not serve as a reasonable debugging case.  I will try to come up with a
simple example that shows the problem.

I will attach more information as I get it.
