Hmm. I've just realised what this error is saying. I should read:

  warning:  switch -mcpu=ep9312 conflicts with switch -march=

ie that -march=NULL

however from the build.log:

[DEBUG]    CT_ARCH_ARCH="armv4t"
[DEBUG]    CT_ARCH_CPU="ep9312

So why is ct-ng apparently not passing my ARCH to configure ?

TIA.
