[Toybox] getconf NPROCESSORS_ONLN broken

As someone who has a vested interest in having less generated code (because
I'd like to stop checking in generated files and use toybox in the AOSP
build[1])... do we even need to do this? How many of these defines are
missing on glibc/musl/bionic? If it's only one or two as I assume, could we
just have the #ifdefs instead?

Or are there actually a large number of these missing?

1. The real problem for me there is that I don't want to replicate all your
scripts in the AOSP build system, but I do want to do the equivalent work.
If it were just the help and flags, I'd probably swallow it --- the library
availability is something I can hard code anyway. But random stuff like
this is something I'd much rather avoid...
