  Log Message:
  -----------
  [libc++] Do not set the `availability=XXX` feature when not testing against a system libc++

Otherwise, the `availability=XXX` lit feature is set even when we're
testing trunk and _LIBCPP_DISABLE_AVAILABILITY is defined, which causes
tests that check for availability markup to be enabled and unexpectedly
pass.
