Looks like all of them.

Actually, it looks like it's just the files whose sources live somewhere else 
(look at envcrc.c, for example).  Those files should be hitting these rules 
inside tools/Makefile:

# Some of the tool objects need to be accessed from outside the tools directory
$(obj)%.o: $(SRCTREE)/common/%.c
         $(HOSTCC) -g $(HOSTCFLAGS_NOPED) -c -o $@ $<

$(obj)%.o: $(SRCTREE)/lib_generic/%.c
         $(HOSTCC) -g $(HOSTCFLAGS) -c -o $@ $<

Do you by any chance have a copy of/link to crc32.c, env_embedded.c, etc. 
sitting in your tools directory, allowing it to match the normal pattern rule?
