With this patch problem still occurs:

Problem for nss_copies.c would be solved if these defines are defined before <cert.h> was included.
It is not enough to change only nss_copies.h file, because the same problem occurs during compilation of other files: 
base64_rsa_pubkey.c, lswnss.c, cavp_ikev1.c, cavp_ikev2.c, cavp_sha.c, cavp_hmac.c, cavp_gcm.c etc.

Maybe a better solution would be to make changes in nspr package.
I have already suggested changes to the package:
