[OpenWrt-Devel] [PATCH] build: explicitly unexport CONFIG_SITE

[Matthias Schiffer]

On systems with CONFIG_SITE in the environment (e.g. OpenSUSE) make will export
the CONFIG_SITE set in include/package.mk by default. This will cause host
builds to get the target site configuration, leading to all kinds of weirdness
(wrong pointer size, wrong endianess).

Fix this by explicitly unexporting CONFIG_SITE. The explicit export for the
target builds overrides the unexport, so the target builds will still correctly
get the site config.

This bug was reported on openwrt-devel by Luiz Angelo Daros de Luca some months
ago, and now I hit it myself.

This should also be backported to BB.
