A question about overrides

[Gary Thomas <gary@mlbassoc.com>]

I have my own distribution layer, built on the poky distribution.
In other words, my layer defines a few basic setups, then inherits
poky to do the rest.

For the most part, I've been successful with this.  The problem at
hand is that for my distribution, I need to support a couple of
different architectures and at the moment, one of them needs to
stay in the stone age tools-wise.  In my distro.conf, I have
lines like these to select those tools for just that architecture:
   GCCVERSION_armv7a ?= "4.3.3"
This works for everything (I've tried), except this:
   POKYLIBC_armv7a ?= "glibc"

* Is there some magic I'm missing with regard to the 'POKYLIBC' symbol?
* Perhaps there's some other way?

For now, I'm overriding this in local.conf, but that requires
hand tuning that I'd like to avoid.

Thanks for any pointers
