Please repost this on dev-tech-crypto. I am on PTO until Wednesday and I
bet somebody else on the NSS team already knows exactly how to deal with
this.
Cheers,
Brian

This is either a bug in the NSS build system, lack of support in NSS
itself for your hardware/software config, or an issue with your
toolchain (your locally built compiler). I don't know enough about
NSS's
build system to know which one it is.
