You can't rely on finding it. Executable images are only required to have segment headers an d the attributes system uses section headers. Section headers can be removed when an image gets stripped.

See PT_ARM_ARCHEXT in the ARM ELF specification (available from infocenter).
As a poor man's test, would it be reliable to test Tag_CPU_name on the resulting u-boot ELF binary at the end of the build? If I read you correctly, you seem to suggest that it would be too fragile?
