Sorry, yes, you're right; I should have looked more carefully.
So we do need a new option; however I think it would be better
for the new option to be a general qemuopts option, like this:

 -semihosting-config target=[native|gdb|auto]

because that then gives us a place to put future semihosting
related config options, and also allows the config files used
by -readconfig/-writeconfig to change this setting. (We can
have -semihosting-config have an implied 'enable=true', so
you don't have to use the old "-semihosting" option if you're
specifying -semihosting-config.)
