prevents MCKERNEL_RLIMIT_STACK from overwriting
...
When mcexec reduces a stack, mcexec stores the original RLIMIT_STACK
in environment variable MCKERNEL_RLIMIT_STACK.
A fix to prohibit overwrite of this time.
Therefore, the value of RLIMIT_STACK of the McKernel's process is
decided in the following order.
(1) If environment variable MCKERNEL_RLIMIT_STACK exists; the value.
(2) A value of RLIMIT_STACK in the mcexec starting.

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.

mcexec: add use of MCKERNEL_RLIMIT_STACK
...
MCKERNEL_RLIMIT_STACK is a environment variable which
specify RLIMIT_STACK value on McKernel.
syntax: MCKERNEL_RLIMIT_STACK=<cur>,<max>
example: MCKERNEL_RLIMIT_STACK=0x800000,-1
cur=8MiB, max=unlimited

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.
