OpenMP: Fix declaration in append-args-interop.c test case
I ran into this while backporting my declare variant/dispatch/interop
patch f016ee89955ab4da5fe7ef89368e9437bb5ffb13 to the og14 development
branch. In C dialects prior to C23 (the default on mainline),
functions declared "float f()" and "float g(void)" aren't considered
equivalent for the purpose of the C front end code that checks whether
a type of a variant matches the base function after accounting for the
added interop arguments. Using "(void)" instead of "()" works in all
C dialects as well as C++, so do that.
gcc/testsuite/ChangeLog
* c-c++-common/gomp/append-args-interop.c: Fix declaration of base
function to be correct for pre-C23 dialects.
