Warner Losh ac77b26215 tests: Test endian.h, byteswap.h, sys/endian.h and both endian.h and byteswap.h together
What's required and not required to be defined is complicated. Write
tests to enshrine it:
	endian.h and sys/endian.h:
		[bl]e{16,32,64}toh
		hto[bl]e{16,32,64}
	byteswap.h:
		{__,}bswap_{16,32,64}
	sys/endian.h:
		{__,}bswap{16,32,64}
		_BYTE_ORDER
		_BIG_ENDIAN
		_LITTLE_ENDIAN
		_PDP_ENDIAN
	endian.h:
		__BYTE_ORDER
		__BIG_ENDIAN
		__LITTLE_ENDIAN
		__PDP_ENDIAN
		__FLOAT_WORD_ORDER

We also ensure that the sys/endian.h conditions hold true when
we include both endian.h and sys/endian.h in either order.

NOT TESTED:	deprecated symbols, internal to glibc symbols
