Your GccTriple is probably nonempty, because Debian’s gcc-4.5 has not yet 
transitioned to the multiarch paths, while Ubuntu’s has.

I’m really quite mystified.  All of this distro/GCC version detection 
nonsense originated in
  http://llvm.org/viewvc/llvm-project?view=rev&revision=118382
(between clang 2.8 and clang 2.9), and has been fixed up several dozen 
times for various distros since then.  You’d think someone would have 
noticed that this isn’t a maintainable solution…
