[Minios-devel] [UNIKRAFT/NEWLIB PATCH 1/1] Add stubs for C++ libraries

[Vlad-Andrei BĂDOIU (78692) <vlad_andrei.badoiu@xxxxxxxxxxxxxxx>]

This patch adds the missing stubs needed by the
C++ llvm libraries. It creates a new locale.c
file for the stubs related to the locales.
This patch adds the missing include
to stddef inside mman.h.
