scripts/gcc-plugins in a more standard way.

the kernel for the build process.

kallsyms: Find all symbols in vmlinux

pnmttologo: Convert pnm files to logo files

conmakehash: Create chartable

The following hostprogs-y programs are only build on demand

These targets are used internally to avoid "is up to date" messages

Let clean descend into subdirs
