    nettle: fix the Segmentation fault
    
    The commit[8ac8fa8ee1 nettle: update to 3.4.1]
    add CFLAGS_append = " -std=c99" to silence the
    below error for native build:
    | ../nettle-3.4.1/rsa-sign-tr.c: In function 'sec_equal':
    | ../nettle-3.4.1/rsa-sign-tr.c:243:3: error: 'for' loop initial declarations are only allowed in C99 mode
       for (size_t i = 0; i < limbs; i++)
       ^
    | ../nettle-3.4.1/rsa-sign-tr.c:243:3: note: use option -std=c99 or -std=gnu99 to compile your code
    | Makefile:263: recipe for target 'rsa-sign-tr.o' failed
    
    But the above change will trigger below Segmentation
    fault:
     # echo -n passwd| nettle-pbkdf2 -i 1 -l 16 salt
     [65534.886509] nettle-pbkdf2[708]: segfault at 1f594260 ip 00007f3332256998 sp 00007fff60d44410 error 4 in libnettle.so.6.5[7f3332244000+1d00]
     [65534.887525] Code: e8 6d db fe ff 44 01 6d 68 48 83 c4 08 5b 5d 41 5c 41 5d 41 5e 41 5f c3 66 2e 0f 1f 84 00 00 00 00 00 49 89 dc e9 68 ff f
     Segmentation fault
    
    So update the logic to CFLAGS_append = " -std=gnu99"
    to fix the issue.
