Largeish refactoring and cleanup of compiler build: Break out native-compiler.sh from root-filesystem.sh NATIVE_TOOLCHAIN=* went away now NO_NATIVE_COMPILER=1 affecting build.sh root-filesystem.sh: Much simplified No more ROOT_TOPDIR, adjust STAGE_DIR=$STAGE_DIR/usr instead. Doesn't build native-compiler, instead copies existing native-compiler else installs library binaries out of cross compiler. Only build make/bash/distcc when we have a native compiler. native-compiler.sh: No more BUILD_STATIC_NATIVE_COMPILER, now built/packaged separately by default (NO_NATIVE_COMPILER=1 to skip), then incorporated into root-filesystem. now static by default, use BUILD_STATIC=none to override This script also makes the (optional) full cross-compiler renamed STATIC_CROSS_COMPILER_HOST to STATIC_CC_HOST Rename cross-compiler stage to simple-cross-compiler
