Darwin mac.local 14.0.0 Darwin Kernel Version 14.0.0: Fri Sep 19 00:26:44 PDT 2014; root:xnu-2782.1.97~2/RELEASE_X86_64 x86_64
>Description:
nss fails to build on 64 bit Darwin because nspr compiles libs in 32 bit mode, even when ABI is set to 64.


>How-To-Repeat:
build with ABI=64 on Darwin
>Fix:
