[PATCH 10/10] Use x86_64 fpu/bits/mathinline.h for i386 and x86-64

["H.J. Lu" <hongjiu dot lu at intel dot com>]

Hi,

This patch uses x86_64 fpu/bits/mathinline.h for i386 and x86-64. OK
to install?


H.J.
----
	[BZ #14117]
	* sysdeps/i386/fpu/bits/mathinline.h: Removed.
	* sysdeps/x86_64/fpu/bits/mathinline.h: Renamed to ...
	* sysdeps/x86/fpu/bits/mathinline.h: This.
