File seabios.mx86-used-note.patch of Package xen

From: Bruce Rogers <brogers@suse.com>
Date: Thu, 4 Feb 2021 11:06:47 -0700
Subject: mx86-used-note

build: be explicit about -mx86-used-note=no

binutils v2.36 switched the default for the assembler's -mx86-used-note,
which caused breakage building seavgabios as follows:
ld: section .note.gnu.property LMA [0000000000000000,0000000000000027]
overlaps section .text LMA [0000000000000000,0000000000006e87]
Fix by explicitly specifying -mx86-used-note=no to assembler in seabios'
Makefile (boo#1181775)
