Future-proof `make clean` under Windows
In Windows cmd, `del foo` succeeds if `foo` doesn't exist, but
`del *.ext` fails if `*.ext` doesn't match any files. Therefore we use
the idiom `if exist *.ext del *.ext` to delete files matching
wildcards.
We've accidentally used `if exist $(some_list) del $(some_list)`, and
that's wrong, because it's only syntactically correct if
`$(some_list)` contains exactly one element. As long as `$(some_list)`
contains actual file names and not wildcards, just use `del $(some_list)`.
