[Buildroot] [git commit] qemu: needs IPv6

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=45fe0d3b4698112a438c6199d73e18c4078c1ad1
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Fixes http://autobuild.buildroot.net/results/f53/f53d4d47a6b65c40c1b122dfad61d9164e533bf0/

Actually only the linux-user code needs it, but with the _CUSTOM_TARGETS
option it is difficult to ensure it only for userland emulation, so just add
it to the main qemu option.

At the same time add the missing wchar/mmu dependencies to the comment.
