 When patchfiles-delete is used on all the patch files listed in
 patchfiles, patchlist in portpatch.tcl becomes empty and errors with:

 {{{
 --->  Applying patches to zlib
 Error: Target org.macports.patch returned: Patch files missing
 DEBUG: Backtrace: Patch files missing
     while executing
 "$procedure $targetname"
 Warning: the following items did not execute (for zlib):
 org.macports.activate org.macports.patch org.macports.configure
 org.macports.build org.macports.destroot org.macports.install
 Error: Status 1 encountered during processing.
 To report a bug, see <http://guide.macports.org/#project.tickets>
 }}}

 It seems like portpatch.tcl should be modified. Right after checking the
 non existence of patchfiles in portpatch::patch_main, the emptiness of
 patchfiles should be checked as well.

 I'm attaching the portfile that caused the issue. It's a Portfile for zlib
 adding a nopatch variant that removes the only zlib patch from patchfiles.
