runc 1.5 depends on libpathrs, so build and install it before compiling runc statically. This requires several adjustments for cross-compilation: - Install cargo/rust for the build (native) arch via apk; only the target libraries go through xx-apk, otherwise the toolchain cannot run. - Pass --rust-target to install.sh, since xx-cargo builds into target/<triple>/release rather than target/release. - Install into the xx sysroot (DESTDIR) so xx's cross pkg-config finds pathrs.pc, and --disable-dynamic since the static build only needs the .a (Alpine's BusyBox install also lacks the -T flag used for the .so). - Work around a go-pathrs build failure under clang's cgo by rewriting the PATHRS_PROC_* int64 temporaries to uint64.
