sched: x86: allow single-depth wchan output
sched.o gets smaller and faster if we compile it with -fomit-frame-pointers,
so make this a config option. The cost is the loss of multi-depth wchan
lookups - but SysRq-T is a sufficient replacement for them anyway, so their
utility is much lower these days.
the size difference is significant:
text data bss dec hex filename
34005 3462 24 37491 9273 sched.o.before
33470 3462 24 36956 905c sched.o.after
