some packages are available in the hackable:1 project:
As the last URL suggests, I haven't updated them for a while though :/

It is not easy, but feasible. I have used the toolchain from the
Emdebian project, and managed to cross-compile libosmocore.
The GSM applications compiled this way did not fully work though. It
would be really nice if OsmocomBB's code could support more toolchains;
I'll try to investigate this myself if I can find some time for this.

Right, this is another issue altogether. There also, it would be great
if some features could be enabled through command-line arguments, but I
also understand why this is not always feasible/desirable even. As for
choosing branches, that's going to be the case for pretty much any
software package in any distribution, and my preference goes for
tracking "stable" code, and therefore track the "master" branch by default.
For the record, my packages were using the master branch indeed, with TX

hackable:1 also features a script to generate ready-to-boot images, and
could be extended to generate live CDs. Since it is based on Debian and
fully open source, GPL compliance should not be an issue.

TBH, I do not want to be that maintainer; but my work should be easy to
grab and maintain.

There is emdebian, but as mentioned, it is (was?) not fully functional
on the target side of things.

Isn't this managed by the code upstream, rather than packaging?

Isn't the library automatically included in the final applicative
images? (I haven't had a look at the project for a while, sorry)

hackable:1 can do that too.
