Description

Use _GNU_SOURCE macro instead of __USE_GNU and define it before including portmacro.h. The reason is that portmacro.h includes limits.h which in-turn includes features.h - this results in __USE_GNU getting incorrectly undefined.

Test Steps

use glibc2.24 and gcc 6.3.0 build sucess
use glibc2.35 and gcc 11.3.0 build sucess
