In the meantime, put the attached patch into
    /etc/portage/patches/dev-libs/appstream-0.11.5/
e.g. as appstream-0.11.5-po_meson_build.patch

We've got a rare case of "over-escaping" in the meson.build for once,
as meson seems to replace '\\' even in commands by '/', so we end up
with '/n' instead of '\n', i.e. "find -printf '%f/n'" instead of
the correct "find -printf '%f\n'". The single '\n' get replaced by
meson by an actual linebreak, so that works too.

Upstream has fixed it in .8 by putting that stuff into an extra script
see https://github.com/ximion/appstream/blob/master/contrib/meson/update-linguas.sh

HTH,

erst jetzt wird mir die Bedeutung des "blutroten Mondes" richtig bewußt.
