Some embedded systems can do without the prctl syscall, saving some space.

This also avoids regular increases in tinyconfig size as people add more
non-optional functionality to prctl (observed via the 0-day kernel
infrastructure).

The first patch moves prctl and all its helpers into a separate source file,
kernel/prctl.c, to allow making it optional via the Makefile without any
ifdefs.  The second patch adds the Kconfig option to make prctl optional.

Josh Triplett (2):
  kernel: Move prctl and helpers from kernel/sys.c to new kernel/prctl.c
  kernel: Support compiling out the prctl syscall
