fail.at woes

[Ralf Wildenhues]

fail.at fails on IRIX and AIX: their linkers will warn about duplicate
symbols when creating a shared library, but they will then go on to
happily discard the duplicate definitions and exit with zero.

So, since the aim of the test is not to exercise the linker, but the
libtool script failure mode, we'll just also pass a bogus object file
to the linker, to make it barf more reliably.  ;-)

OK to apply?

Cheers,
Ralf

        * tests/fail.at: Also pass a bogus object file to the linker so
        it fails more reliably; AIX and IRIX linkers ignore duplicate
        symbol definitions.
