To use gcc-{ar,ranlib} for boot strap we need to add a -B option
to the tool. Since ar has weird and unusual argument conventions
implement the code by hand instead of using any libraries.
v2: Fix typo
v3: Improve comments. Use strlen. Use DIR_SEPARATOR. Add prefixes at
begin.

Change the bootstrap-lto config file to use slim (non fat) LTO..
Speeds up the LTO bootstrap by ~18% on a 4 core system.
This requires using gcc-ar/ranlib in post stage 1 builds, so these
are passed to all sub builds.
v2: Change existing config file as requested by Honza.

This patchkit implements slim LTO bootstrap, which speeds up LTO
bootstrap by only compiling once.
I implemented all of Richard's feedback for the new -B option for
gcc-ar.
Passes full bootstrap and test on x86_64-linux and LTO bootstrap.
Ok to commit now?

Honza's earlier change to the assert at the end of cdtor_comdat_group
was wrong; we really do need to make sure that we've created the '5'
