The file meta-linaro/conf/layers.conf was incorrect (diff attached).
I changed it and now I get this error which I really don't understand:

NOTE: Error expanding variable do_unpack                                                                 | ETA:  --:--:--
ERROR: Error parsing /home/local/poky-amltd/meta-linaro/recipes-devtools/gcc/gcc-crosssdk-intermediate_4.5.1.linaro.bb: invalid syntax (<string>, line 3)

What makes this so hard to understand is that gcc-crosssdk-intermediate_4.5.1.linaro.bb
is virtually identical to gcc-crosssdk-intermediate_4.5.1.bb:

$ diff -u meta-linaro/recipes-devtools/gcc/gcc-crosssdk-intermediate_4.5.1.linaro.bb meta/recipes-devtools/gcc/gcc-crosssdk-intermediate_4.5.1.bb

What does the error above mean and how does it relate to these files/differences?
