Subject: [PATCH] [ng] coverage: custom pre-processes headers in prog_SOURCES

If we specify "foo.my-h" in a prog_SOURCES variable, and then define a
pattern rule to turn a '.my-h' file in a valid '.h' C header file, things
should work out smoothly and as expected (as long as we use BUILT_SOURCES
properly).

* t/suffix-hdr.sh: New test.
