optimize for really small systems
Default to busybox hush for noMMU systems.
Add busybox profiles to choose a minimal busybox
config for noMMU systems.
Add gdb git from ysato for h8/300 simulator.
Change some kernel defaults to off to have a really
small kernel.
For bfin simulator the kernel+initramfs is smaller then
2MB in size.
