What arch is this? I removed VDSO_PRELINK entirely from x86 a while
back, and now x86's vdso has a base address of 0 before relocations,
and everything works just fine.

(Except one ancient glibc, which fails if the vdso is relocated at
all. We no longer support that version of glibc unless you turn off
the vdso entirely.)
