This adds an interface to build packages not only for the target but
also for the build host and/or the compat arch. All it takes for a
recipe is to extend the new PACKAGE_ARCHS (note the plural) variable
with the desired architectures.

The convenience variables PACKAGE_HOST_ARCH and PACKAGE_COMPAT_ARCH are
introduced that fall back to empty strings if the cross-build or
compat-arch features are disabled.

This was too easy to be done already. Even ssbuild seems to work fine 
(Adriaan, please check as well).

I'm currently testing it very successfully to fix/improve our openssl
patching needs, but I think this can also help in the kbuild scenario.
The only thing missing for that is a nice idea how to define per-arch
DEB_BUILD_OPTIONS so that the kernel tool builds can be mapped on build
option, avoiding full builds for only getting those.

Sounds principally good. Thanks.

For the kbuild case I have submitted a similar patch:
[PATCH v2 3/5] dpkg: Add support for additional target and host builds
(Tue, 20 Dec 2022 18:09:19 +0100)

It modifies dpkg-base.bbclass instead of dpkg.bbclass

It uses the SBUILD_HOST variable for the same purpose as this patch
fulfills with the new PACKAGE_ARCH(S) variable. Migration from
SBUILD_HOST to PACKAGE_ARCHS should be possible. But I have not tested
this yet.

My patch will additionally set SCHROOT_DIR depending on
ISAR_CROSS_COMPILE to SCHROOT_TARGET_DIR or SCHROOT_HOST_DIR. That's
what I have not found inside this patch. Since my patch does it in the
dpkg-base.bbclass the schroot configuration is written before running
dpkg_runbuild with the correct SCHROOT_DIR. Doing this in dpkg.bbclass
would need a bit more code - it's not impossible I think.

Best regards

Stefan

It's not needed in my model because schroot variations collapse if you
don't need them (host=target), and the host variant can not only build
for the target but naturally also the host - thus SCHROOT_HOST is
universal in practice.

There is in fact a 3rd proposal that Adriaan explained to me on Friday
(not sure if he shared it on the list before), and that would model the
variation via different (auto-generated) targets (mytarget,
mytarget-native, mytarget-compat). It has some critical point regarding
how to detect non-identical rebuilt arch-all and source packages, but
would otherwise be even more elegant. Adriaan wants to follow-up on that
soon.
