There are similar issues with doing a port to the ARC (R4x00 based)
machines.  The standard only supports ECOFF booting.  netbsd and
openbsd have tools in their tree for this already.

However, converting an image is easy (relatively speaking).
converting a library that might have system calls and oddball system
dependent data structures to deal with is much much harder...
