Yes, you could set this based on the build system architecture no
problem at all.

The reason for this change is to have a single value for native packages
which doesn't change based on MACHINE. That doesn't stop you changing it
based on something specific the native binaries themselves.

The native sysroots are different depending on the build system
architecture anyway so this actually might be a non-issue for you
anyway.

Cheers,
