Thanks!
Please note that even for the calls in the same section, offset of +/-
1M is IMO a bit too small to handle all the cases. Linker has all the
data, so it will relax all appropriate calls, leaving only an extra
unop after relaxation.
I also committed a small testsuite patch, calls are always emitted as
"far" in the assembly.
