Solomon Peachy db6f21e295 hosted: sanitize handling of HOME_DIR
* HOME_DIR is now either "/" or special "<HOME>"
   * target-specific "home dir path" is defined solely by PIVOT_ROOT
 * PIVOT_ROOT path is now defined in toplevel config files
 * Make Samsung YP-R0/R1 and SONY_NWZ use PIVOT_ROOT too
 * Do not prepend PIVOT_ROOT path if the path already has it!
 * Do not play these games for __PCTOOL__ builds
