Gcc toolchain generates the below warning in clone.c,
freestanding.h:44:9: warning: ‘tls’ may be used uninitialized in this function [-Wmaybe-uninitialized] 44 | __syscall(sys_no, __cap(arg1), __cap(arg2), __cap(arg3), __cap(arg4), __cap(arg5), __cap(arg6)) | ^~~~~~~~~ clone.c:392:15: note: ‘tls’ was declared here 392 | void *tls;
Fix the above warning by initializing the pointer.
