The Makefile used to suppress output (by using @), so this target made sense at
the time.
But the Makefile should be simple and make debugging with less abstractions or
fancy printing. The Makefile was made verbose and doesn't hide the build
output, so remove this target.
Prompted by a question on the mailing list about the options target.

Changes to core utils had the side effect of treating the no-clobber option
as an error if the file was not copied if it already exists, thus causing
make to error as well.
Adding this workaround until that issue is addressed.
Alternative solutions:
- always overwrite the file using the -f / --force option
- prefix the cp command with a hyphen which will cause make to ignore
the error, but still report it
- never copy dwm.desktop during the installation process
