This was only rudimentary support anyway; none of the sub-architecture
specific insns were ever supported.
---
As to bfd/ I wasn't really able to spot anything that could go away here
because of only being used by the linker. I'd like to retain some basic
support there, such that e.g. elfedit could still be used to convert an
x86-64 object into a l1om or k1om one, such that users still have _some_
means to create such object files (e.g for their own testsuites of
components they maintain) without needing to go and hex-edit files.
