[testsuite] Skip obj-c++.dg/dwarf-2.mm on Tru64 UNIX

[testsuite] Skip obj-c++.dg/dwarf-2.mm on Tru64 UNIX

[Rainer Orth]

obj-c++.dg/dwarf-2.mm fails on Tru64 UNIX since the target doesn't
support DWARF-2:

FAIL: obj-c++.dg/dwarf-2.mm -fgnu-runtime (test for excess errors)
Excess errors:
/vol/gcc/src/hg/trunk/local/gcc/testsuite/obj-c++.dg/dwarf-2.mm:1:0: error: target system does not support the "dwarf-2" debug format

ERROR: obj-c++.dg/dwarf-2.mm: error executing dg-final: couldn't open "dwarf-2.s": no such file or directory
UNRESOLVED: obj-c++.dg/dwarf-2.mm: error executing dg-final: couldn't open "dwarf-2.s": no such file or directory

To avoid this, the following patch skips the test as is done in
objc.dg/dwarf-2.m.

Tested with the appropriate runtest invocation, installed on mainline.
