Some Makefiles rely on adding values to variables like CFLAGS,
LDFLAGS, etc. For example doing "LDFLAGS += -L../src" does not work fine
when LDFLAGS is defined on the command line of "make".
Commits 297877ab88 ("libselinux utils: override LD{FLAGS, LIBS} for
libselinux.so in Makefile") and 15f2740733 ("Makefiles: override
*FLAGS and *LIBS") recently fixed such issues, by introducing keyword
"override" in the relevant Makefile statements.
In order to prevent the fixed issues from appearing again, add a test
case in Travis-CI configuration file. This case adds on make's command
line minimal definitions for CFLAGS and LDFLAGS and empty definitions
for CPPFLAGS and LDLIBS.
An example of build failure due to a missing override in a required
CPPFLAGS addition is provided on

Travis-CI no longer provides Ruby 2.0 in its Trusty environment (it has
been updated according to
https://blog.travis-ci.com/2017-06-21-trusty-updates-2017-Q2-launch).
Remove this version from .travis.yml.
Moreover Python 3.6 and Ruby 3.4 are available. Test building with them.
Last by not least, pypy virtual environment directory has been renamed
pypy2 (/home/travis/virtualenv/pypy2 is a symbolic link to pypy2-5.6.0).
The updated .travis.yml file has been tested on
https://travis-ci.org/fishilico/selinux/builds/248126824

When building and running tests on a system without SELinux with a
command similar to "make DESTDIR=/tmp/destdir install test", libsemanage
tests fail to build with the following error:
In file included from utilities.h:20:0,
from utilities.c:24:
../src/handle.h:29:26: fatal error: sepol/handle.h: No such file or
directory
#include <sepol/handle.h>
^
Fix this by adding the newly-installed directory under $DESTDIR (using
variable $PREFIX) in the search paths of the compiler.

On systems where $PYTHON is python3.5 (instead of python2 or python3),
pkg-config fails to find the Python package because it is named with a
dash (e.g. python-3.5).
Moreover the build system may have been using the pkg-config
configuration files for the wrong Python version when several Python
with the same major version number are installed (e.g. using python-3.5
on a system with both python-3.4 and python-3.5 and where
/usr/lib/pkgconfig/python3.pc is a symlink to python-3.5.pc).
In order to fix these two issues, compute $PYPREFIX from $PYTHON by
using the full major.minor version.
Moreover update Travis-Ci configuration to grab the relevant
configuration files for pkg-config from /opt/python (for example
/opt/python/3.5.2/lib/pkgconfig/python-3.5.pc) instead of using
system-provided files (/usr/lib/x86_64-linux-gnu/pkgconfig/python3.pc
and /usr/lib/x86_64-linux-gnu/pkgconfig/python2.pc).

Add a configuration file for https://travis-ci.org/. This continuous
integration platform can build the project for several configurations on
Linux, using different compilers, linkers, Python versions and Ruby
versions. An example of build results is available on
https://travis-ci.org/fishilico/selinux/builds/185912863
Even if the SELinux userland libraries and tools project does not enable
Travis-CI integration, the .travis.yml file may be helpful for
contributors who wish to run tests in several configurations.
Current limitations:
- It does not run an OS X build. Travis-CI provides free OS X
environments but it is quite difficult to configure a single
.travis.yml file which defines many Linux environments and some OS X
ones.
- It only runs Ubuntu 14.04 with an x86-64 CPU. This does not test
Android, ARM nor 32-bit x86 configurations.
- It only builds with glibc, not musl or other light C library.
