* configure.in (RUBY_NACL): New M4 func to configure variables for
NaCl.

of Pepper interface types.

"make btest". NaCl can run the built binary by sel_ldr, but it need
rbconfig.rb. So this variable is distinguished from $MINIRUBY.

application.

no waiting thread. If there are 2 or more runnable threads,
the timer thread does polling. Avoid polling makes power save
for several computers (0.2W per a Ruby process, when I measured).
If outside-event such as signal or Thread#kill was occuerred
when the timer thread does not do polling, then wake-up
the timer thread using communication-pipe (the timer thread
waits this communication-pipe with select(2)).
