    build: fix HOST_CONFIGURE_VARS placement
    
    Ensure that HOST_CONFIGURE_VARS are set before the actual configure command
    instead of passing them as configure command arguments.
    
    This change brings host-build.mk in line with package-defaults.mk and makes
    host configure environment variables work as expected.
