[Buildroot] [PATCHv2 12/15] fs/iso9660: add isolinux support

[Yann E. MORIN <yann.morin.1998@free.fr>]

Thomas, All,

On 2015-06-09 00:21 +0200, Thomas Petazzoni spake thusly:
> After all the preparation commits, this commit finally adds the
> iso9660 support itself. Besides adding a new Config.in entry, a little
> bit of .mk code and the isolinux.cfg default configuration, not much
> is needed.

In my previous review, I suggested we always install ldlinux.c32 from
the syslinux package, and into $(BINARIES_DIR)/syslinux, to which you
seemed to agree.

However, it looks like you overlooked that part. ;-)

Still, this patch is good as-is, and can be refined with further
patching later on, hence my reviewed-by tag.

Thanks! :-)

Yann E. MORIN.
