x86/vdso: Use CONFIG_X86_X32_ABI to enable vdso prctl
The prctl code which references vdso_image_x32 is built when CONFIG_X86_X32
is set. This results in the following build failure:
LD init/built-in.o
arch/x86/built-in.o: In function `do_arch_prctl':
(.text+0x27466): undefined reference to `vdso_image_x32'
vdso_image_x32 depends on CONFIG_X86_X32_ABI. So we need to make the prctl
depend on that as well.
