this change is fine, there is another problem especially when doing stage2 build
where it does not respect python settings from env so I was hoping
that it will help to
let it detect python from hosttools which it does but I think this
patch makes things better
I would certainly think lets keep it. I am also mulling to disable
stage2, it will mean that
we dont use LTO to build the compiler itself it might become a bit
slow to compile programs

can you send this as github pull please since CI is triggered on pulls there ?
