Agreed, the key here is to not give up before starting. I'll probably
work on other issues as I find out about them. The copies of libtool
parts are probably the next thing to work on.

In that case I should revise my patch to always use the latest available
config.guess instead of always trying the one in the package first.
Thanks for the info, I was a bit worried about that issue.

That doesn't scale to 30K packages, each with different maintainers both
upstream and Debian. Not to mention all the other distros.

The people who are working on arm64 are employees of ARM Ltd and have
many years of experience with ARM stuff in both Debian and upstream. I
trust them to get the port right the first time. As for the packages, I
would guess that the other 64-bit Debian ports (ia64, amd64 etc) we have
had would have fixed most 64-bitness issues years ago. I would hope that
the port will be ready by the time ARMv8 capable SoCs are shipping.
