Create a generated/build.sh with a single compiler command line to rebuild the toybox_unstripped binary using the existing generated/*.h files. This way we can snapshot the generated/*.{h,sh} from a defconfig build into a "shipped" directory or something, and then people can maybe build on crazy crippled environments like pcbsd that haven't got gmake and put bash under /usr/local so none of the #!/scripts can find it. This solves at least part of the "toybox can build with itself but you need to build toybox first to have the tools to run the build scripts" problem. Next up: work out the minimal config to provide the build tools needed to run an actual build. (This should, eventually, include a "make" command if freebsd's kernel is going to refuse to build with netbsd's "make" and we don't just write off the whole thing as crazy. But it probably shouldn't include commands that #include <linux/*.h> if we are trying to make that work.)
