Subject: [PATCH] Fix build error in binutils 2.36

The build fails in binutils 2.36

[  520s] cat kernel_syms.lst > syminfo.lst.new
[  520s] /usr/lib64/gcc/x86_64-suse-linux/10/../../../../x86_64-suse-linux/bin/ld: section .note.gnu.property VMA [0000000000400158,0000000000400187] overlaps section .bss VMA [000000000000f000,000000000041e1af]

It is caused by assembler now generates the GNU property notes section
by default. Use the assmbler option -mx86-used-note=no to disable the
section from being generated to workaround the ensuing linker issue.
