support/misc/relocate-sdk.sh: allow relocating to any directory

Currently, relocate-sdk.sh must be run _after_ relocating the SDK. There are cases where it is useful to already prepare the SDK _before_ relocating. For example, it allows to prepare a tarball that the user has to extract to a specific, pre-defined location and nothing more than that, which is simpler for the user than requiring the script to be run. In addition, it hides the build directory that was used by the SDK builder (somewhat). Add an optional argument to relocate-sdk.sh that gives the target directory.
