[Buildroot] [PATCH 1/1] boot/syslinux: Fix building syslinux with GCC 14.x

[Lance Fredrickson]

From: Lance Fredrickson <lancethepants@gmail.com>

Add missing stdio.h include. Without it results in the following error under GCC 14.x

../../../com32/lib/syslinux/debug.c: In function ‘syslinux_debug’:
../../../com32/lib/syslinux/debug.c:91:5: error: implicit declaration of function ‘printf’ [-Wimplicit-function-declaration]
   91 |     printf("Dynamic debug unavailable\n");

Upstream: dead (last release in 2014)

Even syslinux had no release since 2014, its mailing list is still more
or less operating: https://www.syslinux.org/archives/
The patch could be sent on that list, in case the project gets a new
maintainer or get forked by somebody else...

See, for example:
https://gitlab.com/buildroot.org/buildroot/-/blob/2024.05/boot/syslinux/0019-stddef.h-add-wchar_t-type-definition.patch?ref_type=tags#L40

I agree, but there's been no commit since 6 years in the Git repo, no
release in 10 years, so I tend to agree also with the fact that
upstream is dead. It's pretty crazy that no alternative
upstream/maintainer has emerged for this project (though its code base
is not amazing, so not very encouraging project to take over the
maintenance of).
