Vincenzo Frascino 50a2610ade lib: vdso: Remove CROSS_COMPILE_COMPAT_VDSO
arm64 was the last architecture using CROSS_COMPILE_COMPAT_VDSO config
option. With this patch series the dependency in the architecture has
been removed.

Remove CROSS_COMPILE_COMPAT_VDSO from the Unified vDSO library code.

This is a generic implementation of gettimeofday vdso.
Each architecture that enables this feature has to
provide the fallback implementation.

This config option helps to avoid possible performance issues
in 32 bit only architectures.
