Pretty sure you tried this one:

Another option may be to leave it out, then add a .note.ABI-tag using
objcopy as part of the ld-elf2flt processing. Bit of a hack I know, but
gets it out of the flatfile, also gives you control over what goes into the
.note.ABI-tag in terms of kernel versions etc.
Actually, that probably won't work as you said linker errors. How about
using a copy of the XYZ.elf file in ld-elf2flt that has the .note.ABI-tag
removed ?
Cheers,
