...
with gcc*9*, all's good.
there are certainly GCC10 bugs that are affecting kernel builds; not surprising
that there might be others.
_completely_ unclear, yet, if THIS^^ is GCC10- or qemu- related ... or perhaps
prjconf on obs ...
anyone had luck with a qemu pkg build wigh GCC 10? or off-the-bat recognize the
issue?
