The elf/tst-dlopen-aout.c test uses asserts to verify properties of the test execution. Instead of using assert it should use xpthread_create and xpthread_join to catch errors starting the threads and fail the test. This shows up in Fedora 28 when building for i686-pc-linux-gnu and using gcc 8.1.1. Tested on i686, and fixes a check failure with -DNDEBUG. Signed-off-by: Carlos O'Donell <carlos@redhat.com>

Verify that incorrectly dlopen()ing an executable without
|
|
__RTLD_OPENEXEC does not cause assertion in ld.so.
