If a non-release architecture is found, and it's known that there is no
native TCG support for that CPU, automatically fall back to the TCI
implementation instead of requesting the user to run configure again
with the --enable-tcg-interpreter option.
This change simplifies building qemu in automatic build environments
(like in my case the debian buildds) because one does not need to
special case on the architectures.
