EFI: Add build environment support for GNU EFI development.
This patch adds build environment for GNU EFI shell development. Note that only the Makefiles used by EFI development are created in this patch, actual OSL is not implemented and ACPICA applications are enabled in this patch. Lv Zheng. Signed-off-by: Lv Zheng <lv.zheng@intel.com>
