Niklas Claesson f9b3b96a63 external: Reorganize to support cross-compilation
On CI it is nice to cache the external dependencies. However if we
always compile them in the same folder we cannot cache for multiple
different architectures. After this commit native compile targets will
still live in `external` but cross compiled versions will live in
`external/<arch>`.
