My plan is to do absolutely nothing more :)

I wasn't aware of these glib MMU changes in the pipeline, but in
general this is my standpoint for a package needing MMU support:

- either someone needs this package on a non-MMU architecture, and:
  a. adds the support him/herself
  b. requests upstream to do it
  c. requests support on the buildroot mailing list

- or there is no explicit request for the package on non-MMU
architectures, and there is for example an autobuild failure. In this
case I think adding a dependency on BR2_HAS_MMU is enough.

In this particular glib2 case, I tend to feel we're in the second
situation. Even though it may happen that the Blackfin developers add
proper support for glib2 on their architecture, I think in the mean
time it can safely be blocked. There is no harm in doing that, on the
contrary: we make sure there are no build failures in such

Best regards,
