Add pkg-config support and include compat/linux* in packaging

Different kernel header versions has been a continuing source of pain.
Though I don't prefer this approach, it seems the most reliable way to
get a build (for the time being) is to bundle the linux/bpf*.h in a
compat directory in the target install location.

To get visibility into that compat directory from another library, one
will need to rely on pkg-config --cflags argument to pull in that compat
directory.

Future work will be to avoid bundling the compat directory if the
version of linux-libc-dev is high enough, or if the presence of the
result of 'make headers_install' from the running kernel can be

Brenden Blanco [Tue, 7 Jul 2015 06:41:23 +0000 (23:41 -0700)]
Add multiple build support styles

* Add RPM and DEB packaging targets (using CPack from CMake) to build
  binary packages for Fedora and Ubuntu targets.
* Add Docker build scripts for each of the above that run the build in
  the right environment (assuming docker is available).
 - In Ubuntu, build against the LLVM 3.7 nightly snapshots
 - In Fedora, build against LLVM 3.7 from git (takes longer)
* Depending on packages installed on the build machine, it may be
  possible to cross-package for other targets without invoking Docker.
* Re-introduce src/cc/compat directory to keep the build stable for the
  time being. Similarly, it was necessary to #define some ugly constants
  that should eventually show up in libc.
* Add a few simple version checks to allow a partially working (really
  tracing only) libbcc in 4.1 kernels.
