documentation: dev-manual - added OE_INIT_FILE and went to 3.4
In the Kernel example appendix I changed some remaining 3.2 kernel strings to 3.4. Also I added the OE_INIT_FILE variable from poky.ent for use instead of the "oe-init-build-env" string. (From yocto-docs rev: 1d9d8d72d197bdd81756eed7fe1529f341de6089) Signed-off-by: Scott Rifenbark <scott.m.rifenbark@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
