Turns out we don't need sed to process the output of gcc -MD. We can just
do this:
read DEPS <filename.deps
The 'read' command in sh actually handles backslashes correctly, so we don't
have to sed them out after all. And then a simple ${DEPS#*:} removes the
"target:" prefix from the dependency line, and we're done!
