gcc47 warnings: A few more fixes

usr.bin/make		pass -fno-address, NO_WERROR=true
usr.bin/monitor		modified source file
usr.bin/netstat		modified source file (2)
usr.bin/sdpquery	WARNS=2, pass -fno-unused-but-set-variable

Make has several evaluations that gcc47 believes will always
(without exception) evaluate to true or false.  Likely gcc47 is not
detecting some cases correctly, so -Wno-address was passed to it.
However, -Werror overrides it, so NO_WERROR had to be set on this
Makefile.

The remaining GCC warnings will be left for swildner to handle.
The -Werror flag will be suppress for GCC47 until further notice.
