Unfortunately the test script accidentally pulled in ninja from epel,
hence not noticing the issue.


There's three issues:

One is easy enough, albeit slightly annoying: 1.8.2 wants the
"depending" file only be named once in a dependency file. Slightly
uglier code in snowball_create.pl, but whatever.

The second is one case of multiple outputs with a depfile:
create_help.pl creates both sql_help.c and sql_help.h. Not immediately
sure what a good solution here is. The brute force solution would be to
invoke it twice, but I don't like that at all.

The last case is the various man directories. That'd be easy enough to
avoid if we generated them inside a man/ directory.
