   By inspecting gdb with ```nm -C $(which gdb) | grep iconv```, in version 
15.1:
   ```
                    U iconv@GLIBC_2.2.5
                    U iconv_close@GLIBC_2.2.5
                    U iconv_open@GLIBC_2.2.5
   ```
   , while in version 16.3:
   ```
   00000000001efb90 t phony_iconv(int, char const**, unsigned long*, char**, 
unsigned long*)
   00000000001efae0 t phony_iconv_open(char const*, char const*)
   ```
   shows that the latter uses its own implementation defined in gdb/charset.cc 
instead of glibc's. This may have something to do with supported charsets?
