hpveer is this device:

I don't know where did you get cm-t35.conf but I guess it's not
selecting right kernel to use, maybe because it's not available in any
enabled layer..

Check PREFERRED_PROVIDER_virtual/kernel in cm-t35.conf but it should not
build linux-hpveer for cm-t35 for sure..

And yes linux-hpveer_git.bb is not optimal in forcing those 
TARGET_CC_KERNEL_ARCH for everybody, because it assumes that everybody
is using default oe-core gcc which is currently 4.6. IIRC Angstrom is
using 4.5 by default.
