From d7761401893497081a3d3542155d0a512a31ef86 Mon Sep 17 00:00:00 2001 From: "Yann E. MORIN\"" Date: Tue, 3 Jan 2012 22:57:25 +0100 Subject: cc/gcc: build core compilers for canadian Currently, we rely on an existing external cross-compiler targetting the target, to build the C library. This can pause quite a few problems if that compiler is different from the one we are building, because it could introduce some ABI issues. This patch removes this dependency, by building the core compilers as we do for standard cross, and also by building the binutils and gcc, for running on the build machine. This means we no longer need to offer the cross-sompiler selection in the menuconfig. Signed-off-by: "Yann E.
