[PATCH v2 1/4] tools/nolibc: Replace ifdef with if defined() in sys.h

[Mark Brown <broonie@kernel.org>]

Thomas has requested that if defined() be used in place of ifdef but
currently ifdef is used consistently in sys.h. Update all the instances of
ifdef to if defined().

Suggested-by: Thomas Weißschuh <linux@weissschuh.net>
