Aaron, Michael, all

I'd probably need some assistance with Travis.  This patchset added
following changes:

however I have to admit I'm not familiar with Travis and the actual
meaning of that configuration (that is it's actual mapping to builds).
I'm getting following CI errors:

1. https://travis-ci.com/ovsrobot/dpdk/jobs/250599578

This is with clang - this patchset should not be run with clang as it is
not supported.  In build "matrix" there is 'gcc' specified but somehow
clang build is attempted.  Please advice me how to change this
.travis.yml to stop that - should I remove entry in "env"?

2. https://travis-ci.com/ovsrobot/dpdk/jobs/250599577
   https://travis-ci.com/ovsrobot/dpdk/jobs/250599591

This is with gcc and meson with shared library and I can't reproduce
this.  The are two problems reported, first a compiler warning which
seems to be not connected at all with the changes:

--8<------------------------
/usr/include/x86_64-linux-gnu/bits/unistd.h:39:9: warning: call to

and a second linker error:

As I've said I can't reproduce none of these problems - are they some CI
issues?

I'd appreciate some help with these.

Andrzej
