[PATCH] x86: Unbreak "make isoimage" with isolinux

[Andi Kleen]

From: Andi Kleen <ak@xxxxxxxxxxxxxxx>

make isoimage doesn't work on recent Fedora versions, the resulting image
always fails with "Failed to load ldlinux.c32 ..."

The fix (originally found by "SebbiUltimate" on reddit) just copies
the file into the iso image.

On Fedora, this is somewhat complicated by the fact that the syslinux
package was split into syslinux and "syslinux-nonlinux", but the
ldlinux.c32 file needed to boot Linux is actually in the
syslinux-nonlinux package(!). So it will only work when that
package is installed, which updates from older versions don't do.
