ada: Silence unused parameter warning on linux

In __gnat_locate_exec_on_path (char *exec_name, int current_dir_on_windows)
the recently added second parameter is for windows only. On non-windows
platforms its usage is removed by the preprocessor and the compiler
reports unused parameter.

gcc/ada/ChangeLog:

	* adaint.c: void parameter on non-windows platforms
