Instead of hardcoding the common files for host utils in the generic
rules, let's declare them in the build.mk file using the same system as
the Linux kernel build.
if a binary "foo" declared in "host-util-bin" or "build-util-bin" has a
matching "foo-objs" variable, it will be build from all objects declared
in "foo-objs" else it uses directly "foo.o" (single source file).
This is preparatory to add new "build" tools sharing common sources.
note: the dependencies on the utils are a bit less fine-grained as a
result of this change, but given the low number of tools, that should be
acceptable.
