afl: Fix afl-qemu build by applying new patches

[Mindavi]

These patches are gathered from different sources,
see also below.
The other patch is required because some implicitly included
files are not included anymore, requiring an explicit include
of <linux/sockios.h>.
This solves issue #41.

Build errors include: SIOCGSTAMP not declared,
SIOCGSTAMPNS not declared and static declaration of ‘gettid’ follows non-static declaration

• qemu/qemu@6d5d5dd

• https://patchwork.kernel.org/patch/10862231/

It would be great if someone could verify this (or help me verify it), I'm not using the qemu build.
Main goal is to make sure afl keeps building in the NixOS repositories for anyone that wants to be able to use the QEMU mode.

I doubt you will get this approved as these patches were not written by you hence you can not accept the google legal stuff on the authors’ patches behalf

[Mindavi]

You're right. I'll close this.

[Mindavi]

Ultimately, this patch is adding one include file and renaming gettid to sys_gettid. I don't think that should give any issues with ownership.

But we'll see.

[valentinbreiz]

qemu still doesn't build itself with the build_qemu_support.sh script..
I think this patch should be merged in master for all users

EDIT: I have another issue with this patch (user/syscall.c:8166: undefined reference to `stime')

[Mindavi]

It would be nice indeed. If you're looking for an alternative, you could look at https://github.com/aflplusplus/aflplusplus.

Let's close this, I guess this is not according CLA anyway.
