I'm always using the same ksh binary, so this does not make any difference

tried, but there does not seem to be significant difference. Also the %check 
script I used was the same script rpmbuild creates from the %check section (in 
/var/tmp/rpm*) and it defines the same environment:

then
  echo "ERROR: /dev/fd does not exist, regression tests skipped"
  exit 0

rpmbuild vs. just %check script executed by the same user on the same machine

I know. I reported that bug
