tools/nolibc: avoid call to wcslen() in _start_c() inserted by clang

Clang may convert the loop to find _auxv into a call to wcslen() which
is missing on nolibc. -fsanitize needs to be disabled for this to
happen.

Use the same pattern as in the nolibc strlen() implementation to avoid
the function call generation.
