perf tools: Fix build by checking if extra warnings are supported
The -Wstack-protector and -Wvolatile-register-var warnings, for
instance, are not supported by gcc 3.4.6.
So fix by doing the same check we already do for -fstack-protector-all.
With this and the other patches in this series, perf builds unmodified
on, for instance, RHEL4.
