[PATCH 2/2] Remove pass in skip_unwinder_tests

[Yao Qi <yao@codesourcery.com>]

Hi,
As we discussed, proc skip_unwinder_tests should not generate any FAIL
or PASS in test summary, so this patch is a follow-up to to remove
'pass', and replace gdb_test_multiple with send_gdb/gdb_expect.  With
this patch applied, these PASS are disappeared in test result.

 -PASS: gdb.cp/nextoverthrow.exp: check for unwinder hook
 -PASS: gdb.cp/nextoverthrow.exp: check for stap probe in unwinder
 -PASS: gdb.java/jnpe.exp: check for unwinder hook
 -PASS: gdb.java/jnpe.exp: check for stap probe in unwinder

gdb/testsuite:

2012-08-23  Yao Qi  <yao@codesourcery.com>

	* lib/gdb.exp (skip_unwinder_tests): Replace 'gdb_test_multiple'
	with 'send_gdb' and 'gdb_expect'.  Remove pass.
