[Buildroot] [PATCH] relocate-sdk: Allow relocating to any location

[Gleb Mazovetskiy]

Previously, the script could only relocate to the current location.

This caused issues for SDK maintainers, as the default target location
(e.g. /opt/my-sdk) would need to be created and the content copied
to it during the build process, which is error-prone.

With this change you can now pass a target location argument to
./relocate-sdk.sh (this does not move the directory).
