bc173baf13 mcexec: add a path prefix for interpreter search 
- When the interpreter is not found,
  add a prefix to the path and retry search.
- the prefix is specified by a environment variable MCEXEC_ALT_ROOT.
- If the MCEXEC_ALT_ROOT does not exist,
  /usr/linux-k1om-4.7/linux-k1om is used as a prefix.
