Differentiate build process for non-amd64 platforms

Browse Source 
- reset `binfmt_misc` is needn't when the building platform is non-amd64 and the
target arch is the same as building platform

- non-amd64 platform doesn't supported cross-build well, and there is no binary of
`qemu-user-static` able to do that, and thus skip the cross-build on non-amd64
platform.
