^ should encourage `mkdir ~/bin`; the debian docker container doesn't
have `~/bin`.

^ holy crap that takes forever. maybe recommend `b4 shazam <lore link>`?

^ should use `~/bin/make.cross` since `~/bin` may not exist in $PATH.

Hi Philip,
I've run into some issues with make.cross when trying to install the
csky toolchain. Maybe you can help?

```
$ COMPILER_INSTALL_PATH=$HOME/0day COMPILER=gcc-12.1.0
~/bin/make.cross W=1 O=build_dir ARCH=csky olddefconfig

Perhaps I MUST update my debian container to 11.7?

Are the 0day toolchains not statically linked? Can they use the ones
from kernel.org which are?
