gcc-plugins/stackleak: Provide verbose mode
In order to compare instrumentation between builds, make the verbose mode of the plugin available during the build. This is rarely needed (behind EXPERT) and very noisy (disabled for COMPILE_TEST). Cc: Alexander Popov <alex.popov@linux.com> Signed-off-by: Kees Cook <keescook@chromium.org>
