catalyst is used to build all stages [natively], from scratch is done by hand

we dont exactly have a document covering initial porting ... about the closest
we have so far is:
i guess i should add some sections for how to bootstrap yourself using

it's fine if you skip some packages like perl ... the critical things really
are the toolchain (gcc/binutils/libc), portage (so python too), and the
lowlevel utils (baselayout/gawk/sed/grep/etc...)
once you have those, you should be able to boot up natively and finish doing
`emerge` on the sh3 machine
