use __TINYC__ define to avoid tinyc compat fixes breaking FreeBSD

To review, tcc does not really use environ, so you have to use clearenv
there. But POSIX, in their wisdom, didn't standardise clearenv yet,
so on FreeBSD, one still needs to manipulate environ on their own.

(If you use tcc on FreeBSD, this may leave you unsatisfied.)
