Bootstrapping new architectures

abuild, since 2.17.0, more or less supports creating cross-compiler and cross-compiling. That still needs a little bit of polishing, same goes to my scripts. All my scripts and example configs are located at http://dev.alpinelinux.org/~tteras/bootstrap

1. Decide on toolchain name (triplet), and update gcc aport to add proper configure flags for it
2. Create cross compiler
   • Write abuild-createcross-$ARCH.conf for it, and use createcross-toolchain.sh to create a cross-compiler.
3. Cross compile minimal system image
   • With above generated toolchain, you can use crossbuild-alpine-bootstrap.sh to create the minimal image.
4. Setup new box
   • If running on new hardware, you also need to prepare kernel images, initramfs and modloop to create the initial bootimage.
   • If running as vserver guest, you can just install the .apks from previous step.
   • Setup builder.
