Rather than a "crufty" test, how about using POSIX sh parameter
expansion, i.e.

$ foo="blah.bar"
$ if [ ${foo##*.} == bar ]; then echo "bar!"; fi
bar!

Therefore, the patch would be something like (untested):

cmd += "if [ ${x##*.} == .md5sum ]; then md5sum $x >> $x.md5sum; fi"

Regards,

Good suggestion! The correct (tested) patch would be:
  if [ ${x##*.} != md5sum ]; then md5sum $x >> $x.md5sum; fi"

Updated patch coming shortly.
