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