Parts of gcc are compiled without libiconv even if it's present in the system
and --with-libiconv-prefix specified correctly.
The reason for this is usage of HAVE_ICONV_H macro.
1. The check for iconv.h in configure does not use the value of
--with-libiconv-prefix option.
2. HAVE_ICONV_H is usel

If used in conjunction with -ffpe-trap=, it could be useful to get a
