I don't like that we build two files in one rule out of the same sources. Let's better do it
like this:


parasite.bin.o: pie.lds.S objs
	ld --oformat=elf64-x86-64 -T pie.lds.S objs -o $@

parasite.bin: parasite.bin.o
	ld -b elf64-x86-64 --oformat=binary -T pie.lds.S $< -o $@

This should work, no?

If yes, then plz make %.bin: %.bin.o dependence with one rule for both parasite and restorer.

Thanks,
Pavel
