I'm getting a couple of test failures from this patch:

  Clang :: Driver/linux-header-search.cpp
  Clang :: Driver/solaris-header-search.cpp

For the latter of the two, the driver picks:

  test/Driver/Inputs/sparc-sun-solaris2.11/usr/gcc/.8/include/c++/4.8.2/sparc-sun-solaris2.11

as the `-internal-isystem` directory, which doesn't exist. It should be finding:

  test/Driver/Inputs/sparc-sun-solaris2.11/usr/gcc/4.8.2/include/c++/4.8.2/sparc-sun-solaris2.11

I think it might be because `GoodVersion.MajorStr` is no longer set.
