qemu now requires gcc >= 7.5, which was the last release in the 7.x
series. We do not have symbols for a gcc dot-version dependency, nor do
we want to add one.
So, add a dependency on gcc >= 8, for both the host and target variants.
In addition:
- Add a missing comment in package/qemu/Config.in.host explaining the
host gcc requirements if host gcc < 8.
Fixes:

[yann.morin.1998@free.fr:
- target qemu also impacted
- propagate to libvirt, gst1-python
- reword commit log that 7.5 is the last 7.x release

Note that system calls made by the emulated user-land are

serviced by the running host kernel. Therefore, if the

kernel headers used by your target are more recent than

the running host kernel, you may run into invalid system

calls, which may yield surprising effects.
