Hmm, didn't know about this till now :(

So, the staging root contains all non-stripped binaries, correct?
Hence building with -g3 and strip should create a staging root with
full debuginfo
but the resulting image will still have stripped binaries without debuginfo?

If this is the case my patch is superfluous :)
