The before.hooks step built libbpfgo-static once on the x86_64 host, producing a single libbpf.a for amd64. The arm64 build override correctly used aarch64-linux-gnu-gcc for the Go CGO step, but pointed at the same x86_64 libbpf.a, causing the linker to fail with 'file in wrong format'. Fix by cross-compiling libbpf for arm64 into a separate output-arm64/ directory using aarch64-linux-gnu-gcc, then pointing the arm64 override at that directory. UAPI headers are arch-independent and are copied from the amd64 build. Signed-off-by: Massimiliano Giovagnoli <maxgio92@pm.me>
