# and used to configure segments in multi-segment.c, etc.  Furthermore,
# relocating the UEFI image during load would result in those symbols not
# pointing to the expected image locations.  So, relocation data is omitted
# from the intermediate UEFI DLL.  This will only result in a
# correctly-functioning build if the UEFI firmware does not attempt to
# relocate the UEFI image, so it may be desirable in the future to revisit
# this design.  To emit relocation data, '-Xlinker --emit-relocs' should be
