While building sh, I get problems that I traced to the awk invocations in
/usr/src/bin/sh/{mkbuiltins,mktokens}.  mkbuiltins does something like

   tr abcd... ABCD... < $temp | awk '{ stuff }'

and mktokens does something like

   sed 's/"//g' /tmp/ka$$ | awk '{ stuff }'

In both cases, awk exits without printing anything, so the generated files
are wrong.  I worked around it by using some temp files instead of the
pipelines.
