Subject: Fix building without scrypt
X-Git-Tag: OpenSSL_1_1_1-pre1~878
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=402f26e6ee56ec295e053d1f6455e910ac398149;p=oweals%2Fopenssl.git

Fix building without scrypt

Building without the scrypt KDF is now possible, the OPENSSL_NO_SCRYPT
define is honored in code. Previous this lead to undefined references.
