-commit 74eeae6c36c1d10a2ef07078ed08c14e637b6d63
-Author: Christoph Moench-Tegeder <cmt@FreeBSD.org>
-
-    explicitly link against libfreebl3 (from nss)
-    
-    contrary to the comment above, rust's usage (via nss-rs) of libfreebl3
-    is not sufficient, and the pkg-config file for nss does not hint at
-    any linking against libfreebl3 either.
