Somewhat related: I find it rather odd that we are very conservative
when it comes to pushing the minimum requirement for GCC, but are very
aggressively requiring newer binutils versions. As a result, it is
quite difficult to find stock systems which can build glibc and actually
have older GCC versions.
If we bump the GCC version requirement to 4.7 (and not beyond), I plan
to restore binutils 2.22 support on x86_64, so that I can test on Debian
wheezy. It looks pretty straightforward to do so.
