FYI: fix up gdb.stabs

[Tom Tromey <tromey at redhat dot com>]

I'm checking this in.

This applies the standard_* cleanup to gdb.stabs.

It also removes some long-dead code to check whether the gdb.stabs
directory was created.

Regtested on x86-64 Fedora 16.

2012-06-26  Tom Tromey  <tromey@redhat.com>

	* gdb.stabs/weird.exp: Remove directory-checking code.  Use
	standard_output_file.
	* gdb.stabs/exclfwd.exp: Use standard_testfile,
	prepare_for_testing.  Remove directory-checking code.
