x86: when building image.iso, use isohybrid if it exists
When building image.iso (make isoimage), use the isohybrid tool if it exists. isohybrid is a script included with Syslinux 3.72 and higher, which creates an image that can be booted either as a hard disk (including removable, e.g. USB disk) or as a CD-ROM. If isohybrid doesn't exist, then this has no effect. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
