Hmm, maybe we can use i486 as build-host and make cross-compilers/binutils for all
other targets. But I prefere
a solution without crocc-compilers that works without tricks.

Because I want to use this set of packages for porting and for building gentoo on
other linux-distros. And this is
the simplest way

Yes, but it is only temporary there and gets replaced with the shared version or can
get unmerged.
