[aarch64-port-dev ] RFR: -Wno-unused-parameter needed for gcc 4.8.2

[Edward Nevill]

Hi,

I t would seem that -Wno-unused-parameter is required in addition 
-Wno-unused in gcc 4.8.2.

Previous versions of gcc seem to cover unused parameters with just 
-Wno-unused.

The following patch adds -Wno-unused-parameter.

Note that I have added the patch to both toolchain.m4 and 
generated-configure.sh in accordance with OpenJDK policy.

All the best,
Ed.
