well, the platformconfigs use v4t toolchain ;)
And my minimalistic BSP also build fine with the provided a5 toolchain. 
But unfortunately the init dies very early ...

Ok, so I'd  say that toolchain is non working unfortunately :(

Could you please ask your co-worker if these flags produce a working 
gcc-4.7.3-glibc-2.16.0-binutils-2.22 arm-cortexa5-linux-gnueabi{hf} and 
used in real live projects?
Maybe the flags are correct but for example the gcc is too old?

I'm interested in cortex-a5 toolchain but will not spend much effort on 
that right now. Maybe I could give it a spin on Christmas vacation ;)

Best regards
