[patch g++.dg]: Disable some weak-tests for mingw-targets

[Kai Tietz <ktietz70 at googlemail dot com>]

Hi,

this patch skips some test, which are trying to test non-existing
weak-variant for mingw-targets.

ChangeLog

2014-11-28  Kai Tietz  <ktietz@redhat.com>

    * g++.dg/abi/anon2.C: Skip for mingw targets.
    * g++.dg/abi/anon3.C: Likewise.
    * g++.dg/abi/thunk5.C: Likewise.
    * g++.dg/abi/rtti1.C: Likewise.

Ok for apply?

Regards,
Kai
