olsr has been disabled on musl three years ago by commit
4bca88c839e54a9140c06010666f5e034127b8b1.
Comments in https://github.com/OLSR/olsrd/issues/6 suggest that the
issue was due to olsr mixing kernel and userspace headers. This issue is
still open.
However, nowadays olsr builds fine on musl under those two conditions:
- musl >= 1.1.16 (i.e. with
http://git.musl-libc.org/cgit/musl/commit/?id=04983f2272382af92eb8f8838964ff944fbb8258)
- kernels >= 4.15 (i.e. with
https://github.com/torvalds/linux/commit/c0bace798436bca0fdc221ff61143f1376a9c3de)
So enable it back on musl with kernels >= 4.15.
