initial native ARM support

The only thing to be fixed was setarch(8) symlinks assumption that is correct for x86 but not for ARM. There's also some hasher(7) setup to be done: mkdir -p ~/.hasher echo >> ~/.hasher/config <<-EOF def_target=arm #cache_dir=$HOME/tmp # depends on RAM/storage configuration EOF ...and of course apt(8) should be properly set up too. An example PoC build on a CM-A510 board (tmpfs): $ make BRANDING=altlinux-centaurus ve/bare.tar.gz ** ARCH: arm 18:10:45 initializing BUILDDIR: build/ 18:10:45 preparing distro config: build/distcfg.mk 18:10:46 starting image build: tail -f build/build.log 18:14:49 done (4:02) ** image: $TMP/out/bare-20120706-arm.tar.gz [23M]
