[PATCH] Fix Neon-0.27-related warning and fix bug introduced in r26820

r26820 introduced a bug which causes that SVN_NEON_0_26 is never defined.

Autoconf expands
if test -n "`echo \"$NEON_VERSION\" | grep '^0\.2[6-7]\.'`" ; then
to
if echo "$NEON_VERSION" | grep -q '^0\.26-7\.' ; then

Additional [ and ] should be placed somewhere outside.

I'm attaching a patch which also fixes Neon-0.27-related warning.

[[[
