The library linter calls load_dependencies() on every ELF file found in the prime directory. For foreign-arch builds (e.g. arm64 snap on an amd64 host) this invokes QEMU via binfmt to run the foreign binary, which fails with 'not a dynamic executable' errors and can SEGFAULT, producing multi-gigabyte core dumps. Add elf_machine field to _ArchConfig and get_host_elf_machine() to elf_utils.py. In library_linter.run(), skip any ELF file whose arch_tuple[2] (e_machine) does not match the host's expected value.
