LO_LIB_DIR is used in nsscrypto_initialize() so must give it a value

Its actual value is irrelevant in the nsscrypto_initialize() case for
iOS, though, as it is used to form a pathname to a hypothetical
libnssckbi.dylib (which does not exist for iOS, as we build NSS
statically), and we patch the NSS code to recognize the nssckbi name
specially in the static build case... Such elegance.
