#<!-- -->143514 broke the `clang-solaris11-sparcv9` bot; from what I can tell that’s Solaris and according to `SolarisTargetInfo::getOSDefines`, the macro `__sun__` should be defined on Solaris, so check for that and don’t try to query the terminal size if it is defined.

Not sure this is the best solution but hopefully it fixes the bot.
