This was the change which finally got my test system (with an older
SUSE 9.0 based user land to boot).  With paravirt older glibc's ld.so 
otherwise throws assertation failures because it somehow can't deal with 
the new placement. This only happens with paravirt enabled.

Binary compatibility is important.

(in fact, its actually very useful so that it picks up the
right libc with Xen-friendly TLS).

AFAIK libc selection comes from the aux vector, not the vdso.
