[meta-freescale] Problems building fsl-image-gui for TARGET_FPU=vfp-neon

I'm trying to build fsl-image-gui for soft float as I am using Mono in a 
project and Mono currently doesn't appear to support hard float.

Git checkouts I'm using are all recent (i.e. within days),

meta-yocto        = 
meta-fsl-arm      = "master:88117e976c16f22b9bbfeb26a52088e31f1d0c4d"
meta-fsl-arm-extra = "master:5b753d3d130ed6932715329d0e887a015e628766"
meta-fsl-demos    = "master:87233da97fe0ead245773e092acb56faa24f3835"
meta-mono         = "master:ceae2e324a03bf2c616c98a69b4e16f7b7a6af03"

I wasn't entirely clear on how to change the tuning to use the neon 
registers instead
of hard float, and in the end I added the following line to local.conf

DEFAULTTUNE_mx6 ?= "cortexa9-neon"

This gets me building with bitbake reporting,

TUNE_FEATURES     = "armv7a vfp neon cortexa9"
TARGET_FPU        = "vfp-neon"

I had some trouble rebuilding and in the end I removed the tmp/ 
directory and restarted
the build. This gets me further but I'm now erroring on gpu-viv-bin-mx6q 

NOTE: Creating RPM package for gpu-viv-bin-mx6q

Can anybody advise whether I'm overriding the default hfp tuning 
correctly, and what might be
going wrong here?

Many thanks,

Alex Lennon
