libc: share time() between minimal libc and armclang libc Introduce a place to share implementations of libc functions that are needed by different libc versions. Place time() in this common location so it can be shared when building for either minimal libc or armclang libc. Signed-off-by: Kumar Gala <kumar.gala@intel.com>

libc: common: add support for iso c11 threads This change capitalizes on newly added support for dynamic thread stacks and the existing pthread support to provide an implementation of the ISO C11 `<threads.h>` API. Signed-off-by: Christopher Friedt <cfriedt@meta.com>

libc: Move gmtime_r into common gmtime_r() has been in the minimal libc for years, however it was not added to expcetions due to an overlook. In order to do this however, it has to be moved first to the common libc area, so that it's available to any libc that may not implement it. Signed-off-by: Robert Lubos <robert.lubos@nordicsemi.no>

libc: Add GCC fno-builtin-malloc flag to common stdlib compilation This prevents the compiler from optimizing calloc into an infinite recursive call. For example a call to malloc + memset zero at GCC -O2 will be replaced by a call to calloc. This causes infinite recursion if the function being implemented *is* calloc. fno-builtin-malloc forces the compiler to avoid this optimization.
