Sort was including the trailing comma and getting the order wrong.
(Specifically, it was comparing "sh," with "sha1sum," and putting sha1sum first
in generated/newtoys.h so the binary search wasn't finding sha1sum. Alas, you
can't feed separate beginning and ending delimiters to "sort -t". The fix is
to copy the appropriate field out with sed, duplicate it at the start of the
string where it's easy to compare, and then remove it again with a second
sed after the sort.
