Remove CVS $Id:$ tags - they make no sense in GIT
Ignore generated files
Fetch latest generate-plist from bsd.port.mk

The difference is that the new code uses NO_STAGE in its logic. Thus we
have to specify -f portdir/Makefile first and then -f ourmakefile on the
command line, so that NO_STAGE gets defined properly.
Workaround ports/187306 inside portsearch

ports/187306: [PATCH] ports-mgmt/portsearch portsearch -u hangs on empty PLIST

Workaround this problem which also exists in bsd.port.mk (whose code is
copied into Mk/Makefile) by quoting the variable PLIST. The problem
itself is caused by ports who set PLIST to an empty value and cause the
generate-plist target from bsd.port.mk to hang (sed(1) waiting for
input on stdin, rather than processing the plist file). For such ports
'make generate-plist' and 'make install' hang, so they are pretty much
broken, but nevertheless - workaround this in portsearch's Mk/Makefile.
