[oe] [meta-xilinx 1/2] xilinx-boot: Refactor recipe to add support for Xilinx ISE 14.1.

[Elvis Dowson]

* Refactor recipe to add support for Xilinx ISE 14.1.
* Fix minor spelling mistakes.
* Add additional log messages.

Ensure that you reconfigure your shell to use bash instead of dash while
building with Ubuntu 12.04 LTS.
