clarify support for functions returning an array

Browse Source 
previously, tcc would accept a prototype of a function returning
an array, but not giving those functions bodies nor calling them.
it seems that gcc has never supported them, so we should probably
just error out... but it's possible that someone already using
tcc includes some header that contains an unused prototype for
one, so let's continue to support that.
