Summary:                    [patch] autoconf check for iconv does not work for
GNU libiconv
Description: 
autoconf check for iconv uses AST_EXT_LIB_CHECK to check that the linker
can find the symbol iconv_open

However GNU libiconv contains:


/* Allocates descriptor for code conversion from encoding ‘fromcode’
to
   encoding ‘tocode’. */
#ifndef LIBICONV_PLUG
#define iconv_open libiconv_open
#endif
extern iconv_t iconv_open (const char* tocode, const char* fromcode);

so the actual symbol in the library is libiconv_open, and the test fails.

  GNU libiconv uses symbol "libiconv_open" instead of "iconv_open".
