elf: Add a way to check if tunable is set (BZ 27069)
The patch adds two new macros, TUNABLE_GET_DEFAULT and TUNABLE_IS_INITIALIZED, here the former get the default value with a signature similar to TUNABLE_GET, while the later returns whether the tunable was set by the environment variable. Checked on x86_64-linux-gnu. Reviewed-by: DJ Delorie <dj@redhat.com> Tested-by: Zhangfei Gao <zhangfei.gao@linaro.org>
