That’s expected.  Guix will not use arbitrary binaries that happen to be
on PATH.  That’s by design.  The bootstrap binaries are at the roots of
the package graph – changes to them would result in the complete graph
to be rebuilt from scratch.

So the binaries have a special role and usually don’t change.  That’s
why the fact that my bootstrap binaries use GCC 5 is not a problem.

You need to cross-build.  x86_64 systems have no i586-gnu persona, so
you can’t use “--system” here.
