  Since we anyway need a wrapper, wouldn't it be more consistent
to set PKG_CONFIG_PATH there instead?

  As long as pkg-config exists, I would wrap this in a
ifeq ($(BR2_PACKAGE_PKG_CONFIG),)

  If for whatever reason, host-pkg-config is also built, the script
will be overwritten.  So to be safe, I'd remove host-pkg-config as well
(as a third patch).

  Although this is just copy-pasted from pkg-config.mk, that's no reason
to break the buildroot conventions :-)

PKG_CONFIG_HOST_BINARY = $(HOST_DIR)/usr/bin/pkg-config
