Rich Felker 19563e1850 add framework to support archs without a native wait4 syscall ...

this commit should make no codegen change for existing archs, but is a
prerequisite for new archs including riscv32. the wait4 emulation
backend provides both cancellable and non-cancellable variants because
waitpid is required to be a cancellation point, but all of our other
uses are not, and most of them cannot be.

based on patch by Stefan O'Rear.
