multiarch/qemu-user-static stopped at QEMU 7.2 (January 2023). Under it,
qmake's compiler probe (`g++ -E -v` in toolchain.prf) returns nothing on the
current gcc 16 toolchain, so every qmake package fails on aarch64 with
"failed to parse default include paths from compiler output" (hype, PR #517).
The same PKGBUILD builds under QEMU 10.2.3 and 11.1.
Register through tonistiigi/binfmt at a pinned tag, on both the ephemeral
builder droplets and the rootful-Docker path of setup_qemu, uninstalling any
existing entry first because the tool keeps an older registration in place.
The tag is now the one place that decides what every emulated build runs
under. Flags stay F and C, which rootless sudo inside the builder needs.
Three opt-in knobs for bin/build, each defaulting to today's behaviour:
OMARCHY_KEEP_BUILD_WORKSPACE=1 keeps build-output/$MIRROR/$ARCH instead
of wiping it, and build/build.sh now folds any packages already there
into omarchy-build.db even when no database exists yet, so packages
built by an earlier job (or a previous, interrupted run) resolve as
dependencies of what builds next.
OMARCHY_SKIP_BUILDER_IMAGE=1 uses the omarchy-pkg-builder image already
present instead of building it, so a workflow can build the image once
with an external BuildKit cache and fan out over package jobs that all
run the same bytes. A missing image is an error, not a silent rebuild.
OMARCHY_DEFER_RUNTIME_DEPS=true builds the omarchy/omarchy-settings pair
with --nodeps, installing only their makedepends and checkdepends
explicitly. The pair depends on each other and on packages a sharded
pipeline builds in other jobs, so they cannot resolve in isolation; the
assembled set is installed in one verified transaction downstream. The
request is refused for anything but exactly that pair, on the host
before Docker starts and again inside the container.
Also fix make_dir_writable: chown -R can succeed on part of the tree
and fail on files a previous container left behind as another uid, and
the old `|| chmod` fallback only ran when chown failed outright. Always
follow with chmod.
