Use the one without assertions for cross-building toolchains, as the
one with assertions is too slow. In practice, one or more of the cross
toolchain builds end up timing out (exceeding the 6 h limit) almost
every day in the scheduled builds, requiring reruns (sometimes
multiple reruns) to complete successfully in time.
(There seems to be a big variation in what actual runner the jobs
end up using; some runners complete the cross builds in around 4 h,
while some are much slower, and seem to require 5-6 hours or more.)
In practice, during the 2 months that I've had scheduled jobs
running on Github Actions, there haven't been any failed asserts
triggered and caught in the cross builds (but once in the cross builds
of ffmpeg, which still keep using a toolchain with asserts enabled).
