Comment (by kencu):

 regarding nss's build idiosyncrasies... no argument. Software should be
 well designed and have toggles for things that might not be broadly
 compatible.

 My experience with taking such issues upstream is -- spotty. People are
 busy. If their code "coverage" encompasses the systems that are commonly
 in use, they are moving on to new features and bug fixes rather than
 adding support for ancient systems.

 But it varies. Feel free to find the upstream for nss and open an issue
 with them!
