The complication and mess stems from the fact that you'll need to
compile components using an absolute prefix to the compiler or have a
script which manages gcc and the binutils as a series of symlinks
(Gentoo Linux does that).

Not all projects unfortunately have wizened up to the fact that
keeping something cross-compile safe is the best way to go so things
may fail unless you have robust compile tools scripts to help manage
