>Description:
It is unclear whether the following difference between evbarm is intentional, as it has led to some other problems described in the mail thread cited below.

# uname -m && nm /usr/lib/libcrypto.so | grep getauxval
evbarm
         w getauxval


# uname -m && nm /usr/lib/libcrypto.so | grep getauxval
