Cleaning up old hacks in gcc

Now, since glibc has been fixed properly to access GCC header files in include-fixed directory, there is no reason to keep old hacks and workarounds in corresponding gcc recipes. The recipes for upstream GCC were cleaned by Khem in his commit, but CodeSourcery recipes were left behind.

It is definitely a trivial patch and probably not worth mentioning here, but I had Bugzilla ticket #4560 opened with the following patch:
