Your problem is simple. I understand that you're making a static binary in 
order to avoid interfering with the brltty already installed on your system. 
That's fine, but you missed one option. You didn't build in the screen driver. 
You can build it in by specifying: --with-screen-driver=lx

There's actually a better way to run brltty from its build tree. In the 
top-level directory of the build tree you'll find a script called run-brltty. 
This script invokes brltty from within the build tree, and passes in options 
which cause it to pick up the drivers, the tables, etc from the build tree. So, 
therefore, the easiest way is to configure with no options, do the make (but 
not the make install), and then run:

   ./run-brltty -bal -dusb:

I don't think that's a problem you need to be concerned with, but it'd be nice 
if you could please include the messages for us to have a look at.

Yes, that's because it has no screen driver. :-)

If you get clever you don't need to do that. Instead of just specifying -dusb:, 
specify the serial numbers as well. For example: -dusb:12345

>brltty: cannot open file: /etc/brltty/de.ttb: Bestand of map bestaat niet
>brltty: cannot load text table: de
>brltty: Text Table: de

This is okay because you built in the text table anyway.

>brltty: checking for screen driver: lx
>brltty: screen driver not loadable: lx
>brltty: screen driver not found

This is your real problem. You can solve it by specifying;

   --with-screen-driver=lx

>brltty: initializing braille driver: al -> USB:

Your Alva itself is being detected just fine.
