After removed "bind" and "postfix" packages, make fs works good, but, make export-sdk gets KeyError: bind-dev...
1. create project
$ ./wrenv.sh -p wrlinux-7
$ cd <project>
$ configure
--enable-board=intel-baytrail-32
--enable-kernel=standard
--enable-rootfs=glibc-std+debug
2. make linux and fs
$ make -C build linux-windriver && make fs
3. remove "bind" and "postfix" package
$ make PKGS="bind" exclude-package
$ make PKGS="postfix" exclude-package
4. make fs
$ make fs
5. export sdk
$ make export-sdk
==> KeyError: bind-dev-9.9.5-r0.0@core2_32
