Use sysconf(_SC_NPROCESSORS_ONLN)
If we're not on ARM and sysconf(_SC_NPROCESSORS_ONLN) doesn't match
sysconf(_SC_NPROCESSORS_CONF), we should use the former, as that is
what the correct count on x86 with hyperthreading disabled in the kernel.
Added some comments on assumptions and future possible problems.
Fixes #1991.
