Have `clang -ccc-cxx` use g++ for linking on Linux

Tested  with 2.7 (Ubuntu packaging) and SVN r111771.

The option -ccc-cxx is supposed to make Clang "Act as a C++ driver", but it
only does that on darwin, auroraux, openbsd, freebd, minix, and dragonfly (the
platforms with Link::ContructJob methods in lib/Driver/Tools.cpp). The attached
patch makes it work on Linux, too (since it seems to do its linking in
gcc::Common::ConstructJob with CCCGenericGCCName).
