V3: add Xilinx MicroBlaze architecture

This is support for Xilinx MicroBlaze processors. MicroBlaze
is a soft core processor designed for Xilinx FPGAs. With this
new architecture ptxdist have to handle dynamic platform
configurations exported by Xilinx design tools.

Some essential changes and extensions inside a few ptxdist core
scripts were made to merge external platform configurations into
the ptxdist platform configuration. That is very important since
the resulting build process have to know about the real CPU
features like hardware multiplier, barrel shifter or similar high
performance accelerators.

So ptxdist knows about this specialty, parse the new platform
directory "xlbsp" and use the content for its own platform
configuration. The content of the new platform directory "xlbsp"
comes from Xilinx design tools and have to be:
  * auto-config.in      (Linux Kernel 2.4 configuration)
  * Kconfig.auto        (Linux Kernel 2.6 configuration)
  * xilinx.dts          (Linux Kernel 2.6 configuration)
  * config.mk           (U-Boot configuration)
  * xparameters.h       (U-Boot configuration)

+	  The Xilinx BSP (shortly "xlbsp") is part of a specific OSELAS.BSP()
+	  and consits of different automatically generated files from the
+	  Xilinx FPGA design. All files for the xlbsp have to be copied from
+	  Xilinx FPGA design project into the OSELAS.BSP() platforms directory
+	  ${PTXDIST_PLATFORMCONFIGDIR}/platforms/xlbsp. Then make a link in
+	  OSELAS.BSP() platforms directory:
+
+		xlbsp_softcpu.in -> xlbsp/Kconfig.auto
+
+	  You have to copy all auto generated files from Xilinx BSP "Third
+	  Party OS (TPOS)" to xlbsp in your OSELAS.BSP(). To get TPOS you have
+	  to include the EDK user repository from MB-Ref into your Xilinx FPGA
+	  design flow.
