Remove kqemu-kmod{,-devel}

The are broken on recent FreeBSD, they are not supported by any qemu version,
they do not build with recent binutils (2.27)

-Subject: [Qemu-devel] [kqemu patch] get Open/NetBSD to work with the kqemu
-	accelerator
-Date: Mon, 5 Nov 2007 22:00:12 +0200
-Message-ID: <281a8e2bec2c45bce8b89bf96457995c.fa6dd951@aerenchyma>
-To: qemu-devel@nongnu.org
-
-[sorry if this is the wrong list, but I haven't figured out any public
- address where I could send kqemu bug reports and patches]
-
-Currently, both NetBSD and OpenBSD are hanging or crashing when running
-on qemu with the kqemu accelerator enabled.
-
-This happens because both systems are using a weird scheme where they
-are loading the GDT table with LGDT up-front (with the limit set to
-the maximum), but are growing the table and actually mapping the memory
-behind it only when needed.
-(see src/sys/arch/i386/i386/gdt.c in both source trees)
-
-That is causing the kqemu accelerator to generate a page fault in
-update_dt_cache() when trying to fill its 'soft' tlb with pages that
-are beyond the real end of the GDT table.
-
-With this diff applied, NetBSD and OpenBSD seem to run fine with
-kqemu + user-only virtualization (I've tried netbsd-4.0-rc2 and
-openbsd 4.2).
-
-Full virtualization (-kernel-kqemu) doesn't work yet for different
-reasons (I think).
-
-Regards,
-Adi
