you can probably use allarch and assign
PACKAGE_ARCH = "${TUNE_PKGARCH}"
I don't remember how many savings will be disabled by this combination.
For multimachine builds these savings could be worse, because better to
spend a bit more time building everything just once per TUNE_PKGARCH and
don't touch it again (until the signature is changed) than keeping it
allarch, but still building it once per TUNE_PKGARCH (because of different
signature and then unpacking it from sstate *every-single-time* you're
building image for different MACHINE (so even without any change to
webmin recipe).

There is one already:
