Comment (by barracuda156):

 `nss` is horribly designed though. It should be quite obvious that cpu-
 specific stuff should have a setting to disable it (and it is obvious to
 most other developers, as other ports has such options), and compilers
 should not be hard-wired. Not only `nss` fails this, it also disregards
 its own settings and `gcc` flags. This problem should have been a matter
 of a trivial fix in the portfile.
 Besides, as you have seen in another ticket, it also failed for `ppc64`,
 where there is no `clang` at all. It is just a bad design IMO.
