tools/perf/build: Remove the volatile-register-var feature check
Namhyung Kim noticed that the volatile-register-var feature check
is superfluous:
> The gcc manpage says this warning is enabled by -Wall, and we add -Wall
> to CFLAGS before doing feature checks. So all gcc versions that support
> -Wvolatile-register-var enables it by default without this check and
> older gcc versions will always fail the feature check.
Remove it - this will further speed up feature checks.
