* configure.in: Use sigsetjmp by default so jumping out of signal
  handlers properly restores the signal mask and SS_ONSTACK flag.
  [ruby-core:54175] [Bug #8254]

* configure.in: Manually check for presence of sigsetjmp. It is not a
  function on some systems, so AC_CHECK_FUNCS cannot be used.

* configure.in: Revert using sigsetjmp by default due to performance
  problems on some systems (eg. older Linux)
