Comment:
.desktop files go directly into `usr/share/applications`, not per package subdirs...

If `$pkgname` fits here, it's for the target file, but I don't think it's a good default either.

Also you'd want to use unquoted `$targetfile`, otherwise it will be passing an empty string as last arg and that's entirely wrong.
