*Env
vim conf/local.conf
BB_NUMBER_THREADS = "8"
PARALLEL_MAKE = "-j 8"
PACKAGE_CLASSES ?= "package_deb"

*problem
1. Create a new build env, and execute "bitbake meta-toolchain-sdk" failed.
   See the following log for detail.
2. But run "bitbake core-image-sato && bitbake meta-toolchain-sdk",
   No such issue, everything is ok.

*analysis
1. The avahi has been installed and then replaced, to install the following
   packages which depends on avahi is failed.
2. The packagegroup-core-standalone-gmae-sdk-target needs some package but
   not added in its RDEPENDS which the packages is created by core-image-sato.

*resolution
1. Run `apt-get -f install' to correct after `apt-get install package' has
   been executed.
2. Modify packagegroup-core-standalone-gmae-sdk-target.bb to add package 
   `opkg' to RDEPENDS
