The sys_foo() naming scheme used by the syscall wrappers may collide with application symbols. Especially as 'sys_' is an obvious naming scheme an application may choose for its own custom systemcall wrappers. Avoid these conflicts by using an leading underscore which moves the names into the implementation's namespace. This naming scheme was chosen over a '__nolibc_' prefix, as these functions are not an implementation detail but a documented interface meant to be used by applications. While this may break some existing users, adapting them should be straightforward. Given that nolibc is most-likely vendored, no unexpected breakage should happen. No in-tree users are affected. These conflicts happen when compiling some of the kernel selftests with nolibc.
