Geoff Levand 3f3b2f2e8c build_image: Run ldconfig in qemu
ldconfig does not work for non-native arches.  Create a new
build_image routine run_ldconfig that uses qemu user emulation
to run the board ldconfig on the board rootfs when the board and
SDK arches are different.

See: http://code.google.com/p/chromium/issues/detail?id=378377

Prior to calling run_ldconfig the board rootfs must have ldconfig
installed.  To arrange this move the call of run_ldconfig to after
the base package install.

Fixes build_image errors like these when building for arm64:

  /sbin/ldconfig: /lib64/libXXX is for unknown machine 183.
