I'm currently working on gas/ld for this config. I hope I get some
acceptable patches sorted out the next days.

Right. Found two days ago and fixed. :-)

Another bug is wrong handling of constants >32bit.

My version of gas _seems_ to work with 64bit addresses.
ld doesn't crash with segfault anymore, but several relocations
are known to be broken. objdump displays now the right software
register names (at least for ELF64).

Again, have some patience.
