+Subject: [PATCH] Add NO_CRYPT to fix build with glibc 2.28
+
+Since glibc 2.28
+(https://savannah.gnu.org/forum/forum.php?forum_id=9205), the obsolete
+functions encrypt, encrypt_r, setkey, setkey_r, cbc_crypt, ecb_crypt,
+and des_setparity are no longer available to newly linked binaries, and
+the headers <rpc/des_crypt.h> and <rpc/rpc_des.h> are no longer
+installed. These functions encrypted and decrypted data with the DES
+block cipher, which is no longer considered secure. Software that still
+uses these functions should switch to a modern cryptography library,
+such as libgcrypt.
+
+So add a NO_CRYPT variable to disable test/crypt
+
+Fixes:
