PATCH: Also check __corei7__ in i386/x86_64 bits/byteswap.h


Hi,

GCC 4.7.0 defines __corei7__ for -march=corei7.  This patch adds
__corei7__ check in i386/x86_64 bits/byteswap.h.  OK to install?

Thanks.

	* sysdeps/i386/bits/byteswap.h: Also check __corei7__.
	* sysdeps/x86_64/bits/byteswap.h: Likewise.
