Fix selftest::test_lexer_string_locations_ebcdic for systems without iconv (PR bootstrap/72844)
selftest::test_lexer_string_locations_ebcdic has this clause:
/* EBCDIC support requires iconv. */
if (!HAVE_ICONV)
return;
leading to a build failure on systems without iconv. This conditional
works in libcpp due to this in libcpp/internal.h:
#if HAVE_ICONV
#include <iconv.h>
#else
#define HAVE_ICONV 0
typedef int iconv_t; /* dummy */
#endif
Fix the problem by ensuring that HAVE_ICONV is always defined within
gcc/input.c.
