Okay, I would suggest to release 1.2.5 and skip the 1.2.6 release.
Then x86_64 support can be added to 1.3.0. Next month I will have
several small holidays where I can work more on x86_64 support. Having
one package for both architectures is something I will try to create
then. I looked into the code for the GCCABI and I think it's doable.

I just found out that in order to create some 64 bit virtual machine I
need VT: http://en.wikipedia.org/wiki/X86_virtualization#Intel_VT_.28IVT.29
My processor doesn't support it, so I can't test x86_64 on other
machines. So i hope someone with a distro other then Ubuntu can help
me testing.
