Fixed 6831323: Use v8plus as minimum required hardware for current Hotspot
  sources

Problem:
Current Hotspot sources use v8plus instructions
so it can't be compiled with -xarch=v8.

Solution:
Use -xarch=v8plus as default for 32-bits VM.
I also fixed the compiler version warning when
building VM for jdk 1.6 with SS11 compilers.
