Log:
  Add Linux compatibility support for `SC_NPROCESSORS_{CONF,ONLN}` as `_SC_NPROCESSORS_{CONF,ONLN}`
  
  The goal of this change is to make it easier to use getconf to query
  the number of available processors.
  
  Sadly it's unclear per POSIX, which form (with a preceding _ or
  lacking it) is correct. I will bring this up on the Austin Group list so
  this point is clarified for implementors that might rely on this getconf
  variable in future POSIX spec versions.
  
  This is something I noticed when trying to import GoogleTest to FreeBSD
  as one of the CI scripts uses this variable on Linux.
