"make examples" on all the examples has failed for some time, but the
compilation of the main libs used to work. I've pulled down a 3.14 kernel
for fedora from koji and confirmed that building with
"RTE_KERNELDIR=/usr/src/kernels/3.14.9-200.fc20.x86_64/" works fine. It's
something that has changed in 3.15 and beyond that is causing clang flags to
get passed in to gcc. I've confirmed that 3.16 also doesn't work.
