Commit 0c3b7e42616f ("tools build: Add support for host programs format")
introduced host_c_flags which referenced CHOSTFLAGS. The actual name of the
variable is HOSTCFLAGS. Fix this up.

This seemed like a typo to the best of my understanding and certain
things wouldn't link properly until this was fixed.

ugh, thanks for finding this.. I think/hope it's typo ;-)
please also change the only perf user of this:
tools/perf/pmu-events/Build:CHOSTFLAGS_jevents.o = -I$(srctree)/tools/include

The final link of fixdep uses LDFLAGS but not the existing HOSTLDFLAGS.
Fix this.

This was another one where I couldn't tell of the use of LDFLAGS was a
typo or intentional, hence keeping both.

I think the replacement (using just HOSTLDFLAGS) should
be the correct fix, moreover fixdep doesn't have any special
link requirements

In preparation for enabling command line CFLAGS, re-name HOSTCFLAGS to
KBUILD_HOSTCFLAGS as the internal use only flags. This should not have any
visible effects.

In preparation for enabling command line LDLIBS, re-name HOST_LOADLIBES to
KBUILD_HOSTLDLIBS as the internal use only flags. This should not have any
visible effects.

For consistency, please rename
$(HOSTLOADLIBES_$(@F))

Now that we have the rename in place, reuse the HOST*FLAGS options as
something that can be set from the command line and included with the
rest of the flags.

Please use HOSTLDLIBS instead of HOST_LOADLIBES.
All of these must be documented in Documentation/kbuild/kbuild.txt
