After a couple cleanup cycles my work on cyrus-imapd and cyrus-sasl has
reached a pretty stable shape. It is not perfect, but it is working.

Here's the status w.r.t. the problems I previously reported.
There is not much news, since I received almost no feedback so far.

I applied my proposed patch to disable saslauthd.

I applied my proposed patch which allows to correctly host-compile
makemd5.
I wonder if it should be applied upstream.

Fixed with --program-prefix=''.

I applied my proposed patch to disable imtest.

Not solved. The good thing is that Дилян Палаузов Dilyan Palauzov
volounteered to update the cyrus-imapd buildsystem
(http://asg.andrew.cmu.edu/archive/message.php?mailbox=archive.cyrus-devel&searchterm=automake&msg=3040),
which would fix these two issues, and possibly also the previous one
with imtest.

I'm going to send a patch series with the current status of my work.
I'd like to know from the buildroot developers whether it is good
enough to be applied or the mentioned problems are too big.
