  Avoid test failures in FreeBSD's GB18030 locale.
  
  The FreeBSD 14.0 iconv converter (GB18030 → UTF-8) cannot convert e.g.
  0x94 0x32 0xBB 0x34 to U+1D100.
  
  * tests/test-c32isalnum.c (main): Skip the GB18030 locale tests on
  FreeBSD, if GL_CHAR32_T_IS_UNICODE (or, equivalently,
  GL_CHAR32_T_VS_WCHAR_T_NEEDS_CONVERSION) is defined.
