x86, vdso: Error out if the vdso contains external references
The vdso is a piece of userspace code which is supposed to be fully
self-contained. Any external (undefined) reference is an error, and
should be caught at compile time. This was giving us trouble when
compiling with -Os on gcc 4.5.0, for example (failed inline).
The need to do a buildtime check was pointed out by Andi Kleen.
