Jiri Olsa 56a2df7615 tools/resolve_btfids: Compile resolve_btfids as host program 
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.

Fixes: 13e07691a1 ("tools/resolve_btfids: Alter how HOSTCC is forced")
