Don't build the c++ compiler on the first stage, saving some time
Build glibc with the compiler we just built (i.e. same stage). With this we
only have to worry about glibc building with one gcc version.

A small update:
*) Add the patches that I forgot on the first patch.
*) Just patch binutils to have a deterministic ar.
*) Bootstrap and install the linker too.
This is an early version of a new build script. Currently it is able to do
reproducible builds of gcc in one machine (they always get the same md5), but
builds done in two different distros are still different.
