	* solib-svr4.c (LM_ADDR_CHECK) <info_verbose>: Use printf_unfiltered
	for the PIC displacement, print also the displacement value.
	(svr4_exec_displacement):  Print DISPLACEMENT if INFO_VERBOSE.

gdb/testsuite/
	* gdb.base/break-interp.exp: Create new displacement parameter value
	for the test_ld calls.
	(reach): New parameter displacement, verify its content.  New push of
	pf_prefix "reach-$func:".  Import global expect_out.
	(test_core): New parameter displacement, verify its content.  New push
	of pf_prefix "core:".  New command "set verbose on".  Import global
	expect_out.
	(test_attach): New parameter displacement, verify its content.  New
	push of pf_prefix "attach:".  New command "set verbose on".  Import
	global expect_out.
	(test_ld): New parameter displacement, pass it to the reach, test_core
	and test_attach calls and verify its content in the "ld.so exit" test.
	* gdb.base/prelink.exp: Remove gdb_exit and final return.
	(prelink): Update expected text, use gdb_test.
