We already have the RETURN_TO macro for this exact use case, and it's already
used in the non-static code path. Use it here too.

This was the last piece of x86 specifics in init-first.c!
(Remember, it started as sysdeps/mach/hurd/i386/init-first.c, with lots of
i386-specific assumptions about how arguments are passed and so on.)
