Types errors during building for arm64 and i586

[FNDenisovna]

Hi, buddies.
I got errors during using your project on arm64 and i586 :
vendor/github.com/anuvu/squashfs/squash.go:185:33: cannot use f.ModTime().Unix() (value of type int64) as int32 value in struct literal
[i586] vendor/github.com/anuvu/squashfs/squash.go:238:12: cannot use uint64(nlinks) (value of type uint64) as uint32 value in struct literal
[i586] vendor/github.com/anuvu/squashfs/squash.go:244:12: cannot use int64(blksize) (value of type int64) as int32 value in struct literal
[i586] vendor/github.com/anuvu/squashfs/squash.go:341:40: cannot use _Ctype_ulong(f.Pos) (value of type _Ctype_ulong) as _Ctype_ulonglong value in variable declaration
[i586] vendor/github.com/anuvu/squashfs/squash.go:598:3: cannot use _Ctype_ulong(sqfs.super.block_size) (value of type _Ctype_ulong) as _Ctype_uint value in argument to (_Cfunc_sqfs_compressor_config_init)

Can you help me with it, please?

For understanding, i need to build Stacker and have buildings require on you there.
