Nathan Froyd eed8699c36 Bug 925222 - part 1 - just check for __linux__ in nsUserInfo::GetDomain; r=bsmedberg
Linux's libc (with _GNU_SOURCE, which we use) and bionic are the only
interesting libcs that define domainname.  The BSDs and OSX don't, and
the latter is the only one we really need to care about.  Since we're
doing multiple configure checks for this one (!) place, it's not really
worth worrying about.  Let's just hardcode this check and be done with
it.
