Changes v8 -> v9:
  - Added SYSDIG_MAKE_ENV to correctly compile kernel driver (thanks Ryan Barnett)
  - Added an explicit SYSDIG_POST_INSTALL_TARGET_HOOKS for installing kernel driver
    as stated in the official documentation [1]
  - Fixed jsoncpp dependency
  - The patch should be in a good final shape now

[1] https://github.com/draios/sysdig/wiki/How%20to%20Install%20Sysdig%20from%20the%20Source%20Code

Changes v7 -> v8:
  - sysdig now alphabetically ordered in Config.in

Changes v6 -> v7:
  - Fixing a nasty mistake in Config.in

Changes v5 -> v6:
  - Patching kernel module makefile to be compatible with buildroot.
  - Patching cmakefile to remove unneed installation of DKMS infrastructure.
  - Removing of unneeded post installation script.
  - Added -DUSE_BUNDLED_JSONCPP = NO
  - Package is now at the bare minimum.

Changes v4 -> v5:
  - Adjusted to 80 columns for sysdig.mk header

Changes v3 -> v4:
  - Changed "depends on" to "select" and fixed selected packages
    dependencies.
  - moved "comment" section to the bottom

Changes v2 -> v3:
  - Changed "depends on" and "select" to simplify package

Changes v1 -> v2:
  - Changed "depends on" with "select" for dependencies (suggested by Baruch)
  - Added comment "sysdig needs a Linux kernel to be built" (suggested by Baruch)
  - Upgreded to recently released 0.1.99
