We're not telling it to look there, it just does. The only way to avoid
this would be to use -nostdinc, but then you have to somehow reconstruct
the other default search paths and tell it to look in them.

So basically, there's not much we can do about it, and the place to
report the issue is <http://bugreport.apple.com/> and/or
<http://gcc.gnu.org/bugzilla/>. (Note that upstream changes to GCC at
this point will likely never be distributed by Apple, since they are
moving to LLVM.)
