support/scripts: add relocate-sdk.sh script for SDK relocation
It will install the script "relocate-sdk.sh" in the HOST_DIR allowing to adjust the path to the SDK directory in all text files after it has been moved to a new location. Signed-off-by: Wolfgang Grandegger <wg@grandegger.com> [Thomas: - Fix shebang to be /bin/sh instead of /bin/bash, suggested by Arnout - Use | instead of \ as a separator for sed expressions, suggested by Arnout, discussed with Wolfgang and others - Remove ./ at the beginning of LOCFILE, suggested by Arnout - Fix comment about the path check being made before doing the replacement, suggested by Arnout - Fix indentation, suggested by Arnout.] Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
