bug#36688: uname no longer accessing hw-platform nor cpu (not updated to use primary info source)

[L A Walsh]

This is a bit weird, as the hw-platform, apparently is i386 or i686, not
sure,
but the cpu is definitely accessible in /proc/cpuinfo.

The following text is from the sysctl call in the
kernel help text for the option:

  CONFIG_SYSCTL_SYSCALL:

  sys_sysctl uses binary paths that have been found challenging
  to properly maintain and use. The interface in /proc/sys
  using paths with ascii names is now the primary path to this
  information.

Apparently my copy of uname is still using the sysctl call(or trying to),
as it comes up with 'unknown' for
       -p, --processor
              print the processor type or "unknown"

       -i, --hardware-platform
              print the hardware platform or "unknown"

This appears to come from:
uname (GNU coreutils) 8.26.18-5e871

Is this fixed in a newer version?

Thanks.
