Alright, but that isn’t going to fix the original issue I reported; 
GccTriple is still "", so it won’t find 
/usr/lib/x86_64-linux-gnu/gcc/x86_64-linux-gnu/4.5/crtbegin.o on x86_64.

I certainly agree that piling distro-specific, GCC-version-specific, and 
arch-specific hacks into ToolChains.cpp is unpleasant; that’s why I think 
we should make the path be configured and tested at build time.

GCC does come with an easy way to find the right path, though:
  $ gcc -print-file-name=crtbegin.o
  /usr/lib/x86_64-linux-gnu/gcc/x86_64-linux-gnu/4.6.1/crtbegin.o
