[meta-freescale] [meta-fsl-arm] Can't build QT5 for i.MX6

I've been trying to build QT5 from meta-qt5 layer without success.
All attempts result in compile errors, as seen in http://ix.io/a2F
I'm using Poky/Yocto + meta-fsl-arm* latest master:
   Build Configuration:
   BB_VERSION        = "1.21.1"
   BUILD_SYS         = "x86_64-linux"
   NATIVELSBSTRING   = "Ubuntu-12.04"
   TARGET_SYS        = "arm-poky-linux-gnueabi"
   MACHINE           = "wandboard-quad"
   DISTRO            = "poky"
   DISTRO_VERSION    = "1.5+snapshot-20140121"
   TUNE_FEATURES     = "armv7a vfp neon callconvention-hard cortexa9"
   TARGET_FPU        = "vfp-neon"
   meta              = "master:97d7e8689ca83a13ea511c0b91bf80974b8750b0"
   meta-fsl-arm      = "master:a899296ac603f549b28200a7c38d4ec4ca5c1ad5"
   meta-fsl-arm-extra = "master:6a8759c593e8cd85f0dccb9e3b6de25adf2b3bb1"
   meta-yocto-bsp    = "master:97d7e8689ca83a13ea511c0b91bf80974b8750b0"
   meta-qt5          = "master:775d77e482f1ea203c78003cccd2547075fd720f"
I've tried different built hosts (Fedora/i586 as well) and other i.MX6
targets, all fail the same way.

The key error from the log seems to be:
/local/wandboard_test/tmp/work/cortexa9hf-vfp-neon-mx6-poky-linux-gnueabi/qtbase/5.1.1-r0/qtbase-opensource-src-5.1.1/include/QtCore/../../src/corelib/io/qurl.h:132:9: error: 
expected identifier before numeric constant
          None = 0x0,
/local/wandboard_test/tmp/work/cortexa9hf-vfp-neon-mx6-poky-linux-gnueabi/qtbase/5.1.1-r0/qtbase-opensource-src-5.1.1/include/QtCore/../../src/corelib/io/qurl.h:132:9: error: 
expected '}' before numeric constant

It looks like somehow 'None' has been defined to be something?

It appears that QT5 has been built, at least at some point, according to
the page http://wiki.wandboard.org/index.php/Building_Qt5_using_yocto_on_Wandboard
I tried to duplicate this using the 'dora' branches with the same
failure as above.

The problem is definitely i.MX related as I can build for other ARM
targets, OMAP3, OMAP4, qemuarm, etc.

Any ideas about this?  You can't imagine how many hours I've been chasing this one!
