Well, I'm very sorry but I cheered just a little bit too early, as I
just found out.

This still holds, and we can also build gnu-make-boot0, diffutils-boot0,
file-boot0, binutils-boot0 using this glibc!

Well, not just yet as I found out.  Building libstdc++-boot0@4.9.4 with
gcc-4.7.4 and glibc-2.16.0 fails with

So, I tried building libstdc++-boot0@4.8.5.  I'm not sure if that's
recent enough to build our main gcc-5, but at least it could be a
necessary intermediate step.  This fails in phase `install'

Feeling slightly discouraged, but I will hammer on.  We're getting
closer and closer...
