Old notes, retained in case still useful
On ppc64, building 32-bit barfs on -z defs when CC is overridden to "gcc -m32". Use the patch at http://www.linuxfromscratch.org/patches/downloads/nss/nss-3.11-zdefs-1.patch and read the instructions in it.
Test Suite: CRL tests
cert.sh uses the local time when creating revocation lists. This can cause a number of tests (130 out of 800) to fail.
cd mozilla/security/nss/tests/cert/ && sed 's/date "*+%Y%m%d%H%M%SZ"*/date -u "+%Y%m%d%H%M%SZ"/g' < cert.sh \ > cert.sh.tmp && mv cert.sh.tmp cert.sh
NSS is unlikely to compile with MAKEFLAGS set to "-j 2". The build process relies on files that it creates for itself very early in the process, so make sure to turn off multi-threaded builds for this one (though it is not recommended that you use the "-j 2" option at all).
