That is OK.

But I don't like to force the users to have _all_ toolchains installed
on their work station. I think the current procedure to MAKEALL _at
least_ two different arches is enough.
Furthermore I don't like to force the users to have a specific toolchain
for submitting a patch to the list. I think it is a benefit to have a
lot of different toolchains on different host systems building the code,
but one should see the build-environment in MAKEALL output to be able to
distinguish between error from patch or error from toolchain.

It is a good idea for some automated build process which runs in the
backyard and spit out some error/warning messages if one patch does
break the build unattended (i.e. the two arches MAKEALL did fail).
