Making resolve_btfids to be compiled as host program so
we can avoid cross compile issues as reported by Nathan.

Also we no longer need HOST_OVERRIDES for BINARY target,
just for 'prepare' targets.

This change has my,
Acked-by: Ian Rogers <irogers@google.com>
but I wonder about cleaning HOST_OVERRIDES. From the patch I sent,
would it be worth adding:
```
--- a/tools/bpf/resolve_btfids/Makefile
+++ b/tools/bpf/resolve_btfids/Makefile
@@ -17,9 +17,9 @@ else
  MAKEFLAGS=--no-print-directory
endif

-# always use the host compiler
+# Overrides for the prepare step libraries.
HOST_OVERRIDES := AR="$(HOSTAR)" CC="$(HOSTCC)" LD="$(HOSTLD)"
ARCH="$(HOSTARCH)" \
-                 EXTRA_CFLAGS="$(HOSTCFLAGS) $(KBUILD_HOSTCFLAGS)"
+                 CROSS_COMPILE=""

RM      ?= rm
HOSTCC  ?= gcc
```
It seems odd passing HOSTCFLAGS this way and mixing HOSTCC as CC with
CROSS_COMPILE set seems open to failure. Perhaps we should just get
rid of this, add something like a HOST=1 option for building the
library and then in the library code do the right thing. That would
fix the issue that libsubcmd and libbpf here are being built reporting
CC rather than HOSTCC, make the build flags in general more sane.

Thanks,
Ian

could you send separate patch with that?

also I'll try to check if we could make prepare libs as hostprogs,
because I think the changes you suggest might depend on that
