Prior to the introduction of Unified vDSO support and compat layer for vDSO on arm64, AT_SYSINFO_EHDR was not defined for compat tasks. In the current implementation, AT_SYSINFO_EHDR is defined even if the compat vdso layer is not built and this causes a regression in the expected behavior of the ABI.
Restore the ABI behavior making sure that AT_SYSINFO_EHDR for compat tasks is defined only when CONFIG_COMPAT_VDSO is enabled.
