[dpdk-dev] [RFC PATCH 07/14] build: reduce indentation in examples build spec

[Bruce Richardson <bruce.richardson@intel.com>]

As with the lib and drivers directories, we can use "continue" keyword to
reduce the indentation level of the majority of the foreach block. At the
same time, we can also replace tab indentation with spaces.
