            Log:
            Remove gdb-rhbz1156192-recursive-dlopen-test.patch

the test relies __malloc_hook, which was deprecated as has been
removed from glibc already. Since the test was never about a GDB
bug, but a glibc bug, and there is no portable way to re-do the
code, the test is just removed.
