That is a bad idea, as void GOACC_data_end (void) is already exported out of
libgomp, so this is an ABI break.
If it is meant as a hack around not specifying the functions to aliasing oracle
properly, and not really needed after expansion to RTL, you could e.g. use an
internal function in GIMPLE and then lower it to normal function call that
doesn't take the argument.
