[Buildroot] [git commit] boot/syslinux: add an option to install a MBR blob

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=6cdb0c4935cebb2d544013f33aa92df430144657
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

This MBR blob will look for an active partition, and boot the bootcode
present in that partition. This can be used to boot an extlinux-prepared
partition.
