Redland - Build error in Ubuntu 12.10 x86

[Tor Lillqvist]

> What is the reason why this is needed though?

The headers from the redland module are no longer copied ("delivered")
to the solver directory, but used from their source directories (in
the workdir/*/UnpackedTarball directory). See
7be158cd53aa7d05a903f566d6148dbfae6e3fbb .

The master branch by definition is where all kinds of development
happens. Occasionally this means breaking incremental rebuilds, making
a "make clean" or "make FOO.clean" or other manual intervention
necessary.
