Fix the endianness test on powerpc so NetBSD/powerpc builds & works.

Browse Source 
NetBSD/powerpc was mis-categorized as little-endian because
_LITTLE_ENDIAN is defined -- what matters on NetBSD is the value
of _BYTE_ORDER.  Retain the old test in the #else clause.

Add some whitespace for added readability.
