This patch contains two fixes:
* if the user wants to install the SDK in a directory that already
  contains a SDK for the same architecture, a warning will be shown;
* when the symbolic links are relocated use -n option. Otherwise,
  symbolic links to existing directories will be created in the
  directory itself;

Cherry-pick commit b751ec137d0228b40a90e9e32b24f5cb5732225b
