Log message:
sysutils/xentools418: Fix build when pandoc is installed

xentools418 does not TOOLS_DEPEND on pandoc, but it looks for it and
finds an installed copy.  This breaks the build because of some latex
issue, and would if it succeeded likely install more files, changing
the binary package.  Therefore, treat usage of a
non-manifestly-depended-on tool as a bug and patch it out.  The patch
is kludgy because configure.ac doesn't support the normal approaches.

With this, package builds on NetBSD 10 amd64 with pandoc present.

Log message:
Update xenkernel418 and xentools418 to 20240909. This brings in Xen 4.18.3

pkgsrc CHANGES:
set O_CLOEXEC (if requested) and remove O_NONBLOCK on /dev/xenevt
set O_CLOEXEC on /kern/xen/privcmd
(both from the freebsd-specific code)

Main changes since 20231116 (Xen 4.18.0):
Fix various bugs, especially in these areas:
- interrupt setup
- error paths

better support for some of the newer CPUs
some performances improvement

Fixes XSA-447, XSA-449, XSA-450, XSA-451, XSA-452, XSA-453, XSA-454, XSA-455,
      XSA-456, XSA-458, XSA-460, XSA-461

Log message:
xentools415, xentools418: fix bug in BSD symbol table support for i386:
When computing the size of the ELF symbol table, the code use
sizeof(Elf64_Shdr) or sizeof(Elf32_Shdr) depending on the kernel being
loaded. But later when computing offsets, the code uses
sizeof(struct elf_sym_header) which contains a union of both Shdr. This result
in an overflow of 64 bytes. Fortunably the code checks the size being copied
with the allocated size and silently ignores the copy if there isn't enough
space. Fortunably as well, the allocated size is rounded up to the next page
boundary, so most of the time there is enough space. Unfortunably, the official
i386 GENERIC kernel from the 10.0 release has the right size to trigger
this bug.
Bump PKGREVISION.

Log message:
sysutils/xentools418: replace /usr/pkg in CHECK_RELRO_SKIP with ${PREFIX}

Currently, the package fails to build if ${PREFIX} is not /usr/pkg,
because one file is not skipped in the RELRO check.

Log message:
sysutils/xentools418: Note that missing man page could be installed

and why it's hard (haskell).

Log message:
xentools418: Update commented-out SDL2 bl3 line and explain

I recently added a patch to force-disable sdl2-config.  Greg Woods
pointed out that if one adds SDL2 bl3 (vs SDL that was commented-out
previously), the package builds.  This commit just updates the
commented-out line and explains this.  (I have no reason to think
including SDL2 is a good idea.)

Log message:
sysutils/xentools418: Force-disable sdl2-config

Resolves failure to build when SDL2 is installed.

Patch tested on netbsd-10 amd64 dom0, which booted and created a domU.
