BIRD version 2.0.9

[Matt Corallo]

Looks like this failed to build on Debian on arm64.

https://buildd.debian.org/status/fetch.php?pkg=bird2&arch=arm64&ver=2.0.9-3&stamp=1649868353&raw=0

To quote:

Error(29): cannot understand prototype: 'const struct f_tree * find_tree(const struct f_tree *t, 
const struct f_val *val) '
     trie.c
