Handle allocated sections, write the full value into the location and only
write the final value.

How did you verify this fix?

What was the reason you avoided writing an ULEB128 value for R_RISCV_SET_ULEB128?

You cannot write a full address into the location, if it only has enough
room for the difference.

I mean, is there any program that you found didn't work without this change?

I was misled by the brokenness of overwrite_uleb. The difference will
work out right even without being able to write the full address.

It is confusing that almost none of the commits are signed.

I don't need to sign the contributor agreement that I worded because "I" and "YOU" are the same person, but I want third party contributors to sign.
