This is something I had first done and tested a while ago, but

It did not show in my running of the testsuite (bootstrap and
testing without regressions on i386-unknown-freebsd10.1), but
in some cases the use of i586 instructions actually avoided
issues for users. And who is running i486 these days?
(And FreeBSD 5 has been out of support for many years; I guess
modern versions of GCC won't work there for completely different
reasons.)
Okay?
Ok.
And okay for GCC 5 after two weeks or so on trunk?
Ok.
Thank you!
