nptl: Add workaround for ASSERT_PTHREAD_INTERNAL_SIZE with GCC 4.9
GCC 4.9 (the minimum current supported) emits an warning for universal
zero initializer ({0}) on ASSERT_PTHREAD_INTERNAL_SIZE:
pthread_attr_init.c: In function ‘__pthread_attr_init_2_1’:
pthread_attr_init.c:37:3: error: missing braces around initializer [-Werror=missing-braces]
ASSERT_PTHREAD_INTERNAL_SIZE (pthread_attr_t, struct pthread_attr);
^
pthread_attr_init.c:37:3: error: (near initialization for ‘(anonymous).__size’) [-Werror=missing-braces]
It is fact GCC BZ#53119 [1] fixed in later version (GCC5+). Since
current branch is closed and there is no indication it will be backports
(comment #20 in same bug report) this patch fixes by using a double
bracket to zero initialize the struct.
Checked on x86_64-linux-gnu with GCC 7 and GCC 4.9.
* nptl/pthreadP.h (ASSERT_PTHREAD_INTERNAL_SIZE): Add workarond for
-Wmissing-braces on GCC 4.9.
