[Buildroot] [git commit] boot/syslinux: fix build with binutils note gnu property section

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=0ca17cdc925124d1b309788518e9d4834b9b2557
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Fixes #11756

This fixes the following build error with newer binutils:

  objcopy -O binary mbr.elf mbr.bin
  perl /build/syslinux/src/syslinux/mbr/checksize.pl mbr.bin
  mbr.bin: too big (452 > 440)

Corresponding bug reports:

 - https://bugs.archlinux.org/task/60405
 - https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=906414

Strip the .note.gnu.property in the linker scripts for the MBRs.
