M1: Fix sed issue.

The MacOS sed doesn't accept semicolon termination for
commands involving defining labels or branching to labels.
This is not a new issue, but it is revealed on newer MacOS
because the sed now complains about unused labels.
In the sed command ':x; /whatever/ { ...; tx }', everything
after the initial : is interpreted as a label.

* Makefile (DEPGEN): Split the sed command's syntax up into
logical lines using multiple -e commands, applying some
formatting with indentation to try to keep it readable.
It looks like multiple -e options just glue together to
make a program, as if they were lines of code; one -e
can define a label referenced by another, and even the
closing brace can be treated as a separate command.
