Hi,
please first change winebuild to support it, make the subject something like "[1/2] winebuild: Add support for -march" and
please update tools/winebuild/winebuild.man.in
In the second patch make use of that new feature in winegcc
Otherwise it looks good, maybe mention why this is needed for Debian/armel
