Subject: [PATCH] tests: rules.mk: scrap legacy suffix search

Instead of just adding elf/bin and friends, actively delete the original
suffixes and include only things we care about.

Before vs After:
make -d | wc -l ==> 4497
make -d | wc -l ==> 932

Now, if only I could turn off the RCS/SCCS support so easily.
