[Crash-utility] Re: [PATCH 0/5] crash: split the cross build CI into primary and secondary groups

The build job cross compiles nine architectures in one matrix, pins ubuntu-24.04, and builds gmp 6.2.1 / mpfr 4.1.0 from unverified tarballs for every architecture. This series reworks it. Patch 1 adds the CROSS_COMPILE triplet mapping for loongarch64 and powerpc64le; the build system rejected both before with "does not support cross compilation". Patch 2 moves the per-arch build into a reusable workflow and builds the primary group (x86_64, x86, aarch64, riscv64, loongarch64) on every push to master, on ubuntu-26.04: x86_64 natively, the rest with the archive's cross toolchains. 26.04 is the first Ubuntu with a loongarch64 cross toolchain and the image ubuntu-latest switches to in November 2026. gmp/mpfr come from the archive where multiarch packages exist and from sha256-verified upstream tarballs elsewhere; if apt refuses the multiarch install because it would downgrade the runner's amd64v3 packages, the target .debs are unpacked instead. Patch 3 adds the secondary group (s390x, ppc64le, ppc64, mips, alpha, sparc64) on ubuntu-24.04, monthly or on demand -- mips has no cross compiler in 26.04 at all -- plus a manual "Build (all arches)" wrapper. Patch 5 lets the arch be picked from a dropdown when dispatching by hand. Patch 4 ("Remove the pr closer workflow") is an unrelated cleanup that was queued on the same branch; drop it if you prefer to review it separately. The per-arch workflow can also be dispatched directly, so one architecture can be built without the rest. Tested with GitHub Actions on the fork: x86_64 (native) and loongarch64 pass end to end on ubuntu-26.04, and the multiarch jobs exercise both the install and the unpack paths. Note: in the future I'd prefer to use github pr for these meta data related changes, and mail list only for code fixes.
