Reopening and changing component to packaging on that basis.

Interestingly, Fedora's packaging looks to produce a similar problematic result
(I get the bug 22740 symptoms at least), maybe due to setting
--with-c-include-dirs to point to GCC's internal headers
<http://pkgs.fedoraproject.org/cgit/llvm.git/tree/llvm.spec?id=2ee1a75aac4cec616ffc803760c25c7e1e7489ce>.

https://bugzilla.redhat.com/show_bug.cgi?id=893817 and
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=594820 suggest that this was
previously necessary to be able to use libstdc++, but perhaps with the
resolution of bug 6907 this is no longer the case.
