Aboriginal Linux has make in the native root filesystem. (Again, last gplv2 version so it's a touch stale now. Back when I did busybox stuff I planned to write a make for that, and now I plan to write one for toybox, but it's a post 1.0 todo item.) There's also a native-compiler tarball that's just the stuff it adds on top of the simple-root-filesystem to make the development environment. (This includes make and bash 2.05b.) Now that my initmpfs patches are upstream, I'm refactoring things to put the simple-root-filesystem in initramfs and splice the native-compiler stuff from hda into the $PATH at runtime, in the init script. But I'm two kernel releases behind, and should probably ship a 3.15 version before doing much more development... Rob (P.S. Making a stripped down linux from scratch build based on busybox and uclibc is why I got into busybox development in the first place. That's why I wound up doing so much work on it I got the maintainership handed to me for a bit. Now I'm doing it all again in toybox because Android won't use busybox because it's under the GPL.)
