Subject: Improve the checking of sed by adding some common GNU sed
 installation names (gsed/gnused), checking for a basic OS X sed feature in
 command line option handling, checking the actual result of the sed run
 against the expected result, and placing common code for the check under
 toolchain/dependencies/.  (Heikki Lindholm)
