[Bug java/31932] New: no values accepted for --encoding options except UTF-8

["serg at vostok dot net" <gcc-bugzilla at gcc dot gnu dot org>]

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 useless because check for libiconv uses iconv.h anyway.

3. HAVE_ICONV is changed in some source files like this:

#ifndef HAVE_ICONV_H
#undef HAVE_ICONV
#endif

- which is inherently incorrect in and of itself: any information produced by
configure must not be changed in the source code. If configure tests don't work
right - fix them, but all source code must be compiled with the same global
settings.
