[PATCH] getenv.c: Avoid check for unknown endianness.

[Carlos O'Donell]

This is a small code cleanup.

We only ever support big or little endian, and we should not 
check for a weird 3rd byte order. If such an error check were to 
happen it would happen in a central location or at configure
time.

The following patch removes check for the big endian case, and
makes it assume that !__LITTLE_ENDIAN == __BIG_ENDIAN.

No regressions on x86_64.

OK?

	* stdlib/getenv.c (getenv): Assume __BIG_ENDIAN in the
	else clause and remove check for non-standard endianness.
