Fixes two locations where unaligned accesses will cause bus errors on architectures that are strict about such accesses, namely sparc. The first is in swab32_into, which is called with an offset of +1 into an unsigned char array from mklink_fs. The second is in add2fs_from_tarball when checking the validity of a tarball, which casts a string from an unaligned position inside a struct to a long. After these changes, the test suite passes on sparc.
sizeof(long) != 8 on 32-bit.
