[PATCH] kbuild: export HOSTPKG_CONFIG like Linux does

[PATCH] kbuild: export HOSTPKG_CONFIG like Linux does

[Ahmad Fatoum]

Since Linux commit d5ea4fece450 ("kbuild: Allow kernel installation packaging
to override pkg-config"), Linux supports overriding the pkg-config
executable via the HOSTPKG_CONFIG variable.

barebox already had that support, but with a differently named PKG_CONFIG
variable. For compatibility with build systems assuming Linux Kbuild and
to allow easier sharing of code (e.g. scripts/kconfig), define
HOSTPKG_CONFIG for barebox as well.
