It's unclear whether ELF will be useful for the uClinux project (it's relatively complicated, so we're currently using a custom -- and trivial binary format). In any case, it looks like we may be able to use a few trick to get located code (code that does not have to be PIC, since it is linked to the exact address in the target at which it will run.)
