Niclas Zeising cad8743cbb Fix illegal instruction when running in kvm/qemu
Fix illegal instruction when running xserver in kvm or qemu (and possibly
others) virtualisation.  This is solved by disabling sse instructions while
compiling the xf86SlowBcopy (don't ask) function.

This fix was originally committed by dim as r396167 in 2015, and then most
likely accidentally removed in r433863 in 2017.

Bump portrevision

Original commit message:

> Disable use of SSE instructions in Xorg's xf86SlowBcopy() function.
>
> When such instructions are used to copy data from/to mapped video
> memory, some hypervisors (e.g. KVM, Microsoft Hyper-V) can generate
> SIGILL or SIGBUS exceptions, causing Xorg to crash.
