[OE-core] dpkg's admindir: /var/dpkg or /var/lib/dpkg?

[Cui, Dexuan]

Hi, I happened to find a bug: in target,  "dpkg --list" shows "dpkg-query: failed to open package info file `/var/lib/dpkg/status' for reading: No such file or directory"

Actually the files(status and available) does exist, but not in /var/lib/dpkg/ -- they're in /var/dpkg/. "ln -s /var/dpkg/{status, available} /var/lib/dpkg" can resolve the issue.

grepping '/var/dpkg' shows there are many files(package_deb.bbclass, rootfs_deb.bbclass, populate_sdk_deb.bbclas, apt.conf ) in which '/var/dpkg' is used and /var/lib/dpkg is not used at all.

However, looks dpkg's default admindir is /var/lib/dpkg -- e.g., Ubuntu uses this.

What should we do? Looks fixing the package dpkg's admindir in the do_configure needs the least coding.

Thanks,
