We spend an awful lot of CI time building QEMU, even though most changes don't
touch the subset of tools/libs/ used by QEMU. Some numbers taken at a time
when CI was otherwise quiet:
With Without
Alpine: 13m38s 6m04s
Debian 12: 10m05s 8m10s
OpenSUSE Tumbleweed: 11m40s 7m54s
Ubuntu 24.04: 14m56s 8m06s
which is a >50% improvement in wallclock time in some cases.
The only build we have that needs QEMU is alpine-3.18-gcc-debug. This is the
build deployed and used by the QubesOS ADL-* and Zen3p-* jobs.
Xilinx-x86_64 deploys it too, but is PVH-only and doesn't use QEMU.
QEMU is also built by CirrusCI for FreeBSD (fully Clang/LLVM toolchain).
This should help quite a lot with Gitlab CI capacity.
