Here's a patch which fixes this, but I highly doubt this will be blessed by Faré as being anywhere close to the proper way to do it... (i'm just removing non-existent files from the list of fasl-files passed to combine-fasls).

Oops, it looks like I didn't re-test the "workaround" case. That is, a system with some :depends-on but no :components.

Such systems now fail to build either 'asdf:fasl-op or 'asdf:monolithic-fasl-op.

The 'asdf:fasl-op gives the "WTF -- no input files?"

Of course there are no input files -- there are no :components. So maybe the WTF error is correct behavior in the case of 'asdf:fasl-op. But in case of 'asdf:monolithic-fasl-op, I think the correct behavior should simply be to omit the "empty" fasl, which is apparently what it had been doing previously.

This can be replicated with for example the current master of gendl. It's allowed for a defsystem to have only :depends-on and no :components, isn't it?
