tune-*: add OPTDEFAULTTUNE variable

* bitbake.conf has OPTDEFAULTTUNE with weak default value of DEFAULTTUNE
* this way distribution policy can set DEFAULTTUNE = OPTDEFAULTTUNE to
  build always with more specific tune (which includes -mtune
  parameter) without listing DEFAULTTUNEs for all MACHINEs supported by
  distribution.
* or it can set such tunes only for some packages
  DEFAULTTUNE_pn-foo = "${OPTDEFAULTTUNE}"
* or it can include meta/conf/distro/include/optimized-tune.inc which
  will be used to share knowledge which packages are worth building with
  specific -mtune
