    security/putty: fix aarch64 build on clang 10.
    
    clang 10 (FreeBSD 12.3) does not support vaddq_p128 and similar
    ARM NEON intrinsics, but clang 13 (FreeBSD 13.1) does.
    
    Abuse the HAVE_NEON_PMULL cmake test to disable aesgcm-neon.c
    unless vaddq_p128() is available.

    /wrkdirs/usr/ports/security/putty-nogtk/work/putty-0.78~pre20220922.9fcfd67/crypto/aesgcm-neon.c:125:16:
    warning: implicit declaration of function 'vaddq_p128' is invalid in C99 [-Wimplicit-function-declaration]
            ctx->acc = vaddq_p128(ctx->acc, load_p128_be(coeff));
    
    (cherry picked from commit 8fc6b69f47e7ee7da005f8b59fc10522d287740b)

+This is a crude hack to avoid aesgcm-neon.c on FreeBSD 12.3,
+which does - by way of clang 10.0.1 - not offer vaddq_p128()
+through arm-neon.h. clang 13 as of FreeBSD 13.1 does.
