603ef85454 mcexec: add a upper limit of the stack size 
- When the stack size is greater than 1 GiB, reduced to 10 MiB.
- To achieve a reduction of the stack, restart itself using the exec().
- By using the environment variable MCKERNEL_RLIMIT_STACK,
  tell to McKernel the stack size of the original.

cur=8MiB, max=unlimited

- When the interpreter is not found,
  add a prefix to the path and retry search.
