Makefile: -aarm64 to dpkg-buildpackage for arm64 cross-builds
dpkg-buildpackage -b uses the host architecture for both naming
and packaging, ignoring dotnet's --runtime flag. The cross-build
for arm64 therefore produced postit_*_amd64.deb (with arm64 .so
inside, weird) instead of postit_*_arm64.deb. Worse, the
subsequent arm64 step then saw no arm64 .deb in /src/ and failed
with 'Missing .deb files'.

Pass -aarm64 (or -aamd64) to dpkg-buildpackage so it tags the
.deb with the right Debian architecture. Linux-arm64 dotnet
runtime publishes binaries for arm64 already; we just need the
.deb filename to match.

Caveat: this also tells dpkg-buildpackage that the build is
targeting arm64, which may cause it to look for arm64-specific
tooling. In practice for this packaging the only tool is
objcopy/strip (both disabled for the cross-build) and dpkg-shlibdeps
(which we already enable with multi-arch libc:arm64 etc.).

Makefile

# Makefile for the postit Debian package.
#
# Targets:
# make deb : build a .deb in the parent directory (or
# $POSTIT_OUT_DIR if set). Equivalent to
# dpkg-buildpackage -us -uc -b.
# make test : run the non-regression tests under tests/.
# The fetch test pins the upstream Git mechanics
# that previously regressed on tag-vs-branch
# handling (1.0.1-rc02). Set SKIP_NETWORK_TESTS=1
# to skip the GitHub-egress parts.
# make clean : rm -rf build/ and the per-package staging tree
# under debian/postit.
# make source : fetch the upstream yavsc source tree under
# build/yavsc-src (no packaging step). Useful for
# debugging the publish step.
#
# Environment overrides (or pass on the make command line):
# POSTIT_GIT_URL default: https://github.com/pazof/yavsc.git
# POSTIT_GIT_TAG default: 1.0.0
# POSTIT_RUNTIME default: linux-x64 (override to linux-arm64 etc.)
# POSTIT_OUT_DIR default: $(CURDIR)/.. (artifacts land here)
POSTIT_GIT_URL ?= https://github.com/pazof/yavsc.git
POSTIT_GIT_TAG ?= 1.0.6
POSTIT_RUNTIME ?= linux-x64
POSTIT_OUT_DIR ?= $(CURDIR)/..
