Currently we build vDSO handling code for all archs provided in the source code having some "common" parts inside pie/vdso.c, pie/vdso-stub.c, vdso-stub.c and vdso.c. This were more or less well but in new linux kernels (starting from 3.16 presumably) the vDSO has been significantly reworked so every architecture must have own vDSO handling engine (just like the kernel does). So in this patch we move vDSO code to arch specific and because aarch64 actually doesn't implement proxification yet due to kernel restrictions -- we drops it out. When there will be kernel support we bring it back in proper arch/aarch64 implementation.
