Oswald Buddenhagen 8185fe84a6 fix up detection code for compiler defaulting to c++98
- remove the unconditional CONFIG+=c++11 from default_pre.prf, so the
  change actually has any effect
- fix up the description fields somewhat

this amends 091df96fb8, which was rushed in without maintainer review.
