[Bug libc/10162] New: stratcliff test segfaults on ia64

glibc 2.10 has added a new test for memchr() in stratcliff. This new test fails
on ia64, which has its own assembly version in sysdeps/ia64/memchr.S.
It looks like this assembly version does some prefetch, and crosses the page
boundary, causing the segfault. It should be possible to do prefetching while
not triggering page faults on ia64, but I don't know enough ia64 assembly to be
able to modify this code myself.
