The kernel work fine with NPTL and the current libc before the patch.
That should qualify as nothing unusual.  There certainly is not code
which sets AT_SYSINFO etc.

What I found so far is that it i fails inside libc, not ld.so.  I.e.,
the startup already left ld.so when it bombs.  In which, the test
program I have (io/pwd, one of the simplest programs there is) fails in
the printf code.  The fstat(1,...) is executed, then it fails.  In a
correct program the next step would be an mmap() syscall.  mmap itself
isn't broken since ld.so already performed a ton of those calls (though
not exactly the same code, it uses the copy in ld.so itself).
