Rework cross toolchain bootstrap

This patchset drops one gcc bootstrap phase. It has been possible because of some work upstream glibc to drop build time dependency on libgcc_s and libgcc_eh

I have built all possible images in OE-Core for all qemu machines all of them built fine except *-rt and *-initramfs which failed due to unrelated issues. I have built from scratch as well as built from sstate. Seems to go ok.

The following changes since commit 04568d1f18250d531aad5d286157d2d559083520:

qemu: Fix broken accidental path move (2012-08-20 17:25:21 +0100)
