* configure.in: Recognize --enable-nss-crypt.
* config.make.in: Add nss-crypt entry. * crypt/Makefile: If nss-crypt==yes, don't build md5.c, sha256.c, sha512.c. Don't run md5test, sha256test, sha512test. Pass -DUSE_NSS and include path for NSS directory to compiler for md5-crypt, sha256-crypt, sha512-crypt. Link libcrypt.so with -lfreebl3. * crypt/md5-crypt.c: If USE_NSS is defined, don't use local hash function implementation, use NSS. Introduce wrappers around the hash function calls. Little code size optimization. * crypt/sha256-crypt.c: Likewise. * crypt/sha512-crypt.c: Likewise. * scripts/check-local-headers.sh: Ignore nss3 directory. * configure.in: Rename pic_default to libc_cv_pic_default. * config.make.in: Likewise.
