Fix incorrect check for iPhone macro in hwconsts.h
TARGET_OS_IPHONE is always defined when building on Mac OS, so the define was wrong. This macro expands to either 0 or 1, so a simple #if should be enough.

/*
LITTLE_ENDIAN_UNALIGN means:
1) CPU is LITTLE_ENDIAN
2) it's allowed to make unaligned memory accesses
if LITTLE_ENDIAN_UNALIGN is not defined, it means that we don't know
about these properties of platform.
