To be clear on how to use this - I added the meta-linaro layer to my
poky tree and added these to my <MACHINE>.conf:
   GCCVERSION = "4.5.1.linaro"
   SDKGCCVERSION = "4.5.1.linaro"

When I tried this, I got these errors:
NOTE: preferred version 4.5.1.linaro of gcc-cross not available (for item virtual/arm-poky-linux-gnueabi-gcc)
NOTE: preferred version 4.5.1.linaro of gcc-runtime not available (for item virtual/arm-poky-linux-gnueabi-compilerlibs)

What did I miss?
