rootfs rebuild takes too long when testing new toolchain builds
When rev'ing the toolchain it needs to be tested against the kernel and rootfs. However, a full rootfs built with Buildroot can take many hours to rebuild (probably because it has far too much junk enabled in it, but that's for RM #232). I need a faster rootfs build to verify the toolchain.
The way to do this is to build Busybox alone, possibly with a stripped down applet list, and packaged as an ext3 image just like Buildroot is. This means copying over some of the buildroot targets like buildroot-ext3 and then testing ways to specify a custom config file for the stripped down version.
