We only had one package for building both the bootloader and the installer, i.e. target and host code. It used always the host compiler. Split the package into syslinux and syslinux-installer-native, require both for a cd bootable image. git-svn-id: https://svn.o-hand.com/repos/poky/trunk@5539 311d38ba-8fff-0310-9ca6-ca027cbcb966
