We have had SMP support in TCG for quite a while; remove
the reference to a necessary in-kernel accelerator.

Note that I was tempted to enumerate here the MTTCG-compatible
ISAs, but I decided against it because (1) most popular target ISAs
have been converted, and (2) I doubt we'd do a good job in keeping
the list up to date.

Hi,

This series failed the docker-mingw@fedora build test. Please find the testing commands and
