Travis CI setup

Travis CI setup

[Ciro Santilli]

I've made a Travis CI build at:
https://github.com/cirosantilli/binutils-gdb/tree/gdb/travis

It runs in an Ubuntu 12.04 AMD64 machine.

It finishes in 20 minutes with 30 errors:
https://s3.amazonaws.com/archive.travis-ci.org/jobs/72605568/log.txt ,
less than the 46 on my Ubuntu 14.04 machine, and the same Buildbot
commit result.

With parallel tests make -j$(ncpus) it runs in 4 minutes, but the
error rate goes up.

Best of all: free testing infrastructure, that can be used by anyone
to test commits on branches before they are merged.

Let me know if the build steps on the .travis.yml can be improved
somehow to reduce false errors.

Hi Ciro,

You could install the systemtap-sdt-dev package, that would allow
running the tests that currently exit early with:

  fatal error: sys/sdt.h: No such file or directory

They probably show as untested or unsupported right now, so it won't
reduce the number of failures, just raise the number of passes.

Thanks for the tip! I have added it as well, and the number of tests did go up.

I think on 14.04 apt-get build-dep installs it, but apparently not in 12.04.
