What you actually want here is RTE_TARGET=build, as the Makefile looks for the
${RTE_TARGET}/.config file, it doesn't just parse whatever target file you
specify.

That begs the bigger point, RTE_TARGET will always be =build, so why not just
add a top level make rule for the examples subdirectory, then RTE_SDK and
RTE_TARGET will just be automatically set.
