> 
> REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3308
> 
> The EDK II Build Specifications do not restrict the set of
> CPU architectures that can be supported.  Remove places in
> the EDK II that assumes a fixed set of CPU architectures.
> 
> Update EFI_REMOVABLE_MEDIA_FILE_NAME to allow it to be
> predefined in tools_def.txt or a DSC file [BuildOptions]
> section using a *_*_*_CC_FLAGS statement.
> 
> Add support for the following two defines.  If neither are
> defines, then preserve the current behavior.  If either is
> defined, then compare these 16-bit values to Machine in the
> EFI_IMAGE_MACHINE_TYPE_SUPPORTED(Machine) and
> EFI_IMAGE_MACHINE_CROSS_TYPE_SUPPORTED(Machine) macros.
> 
> * EFI_IMAGE_MACHINE_TYPE_VALUE
