utf8.c: print warning about disabled iconvmk/utf8-no-iconv-warn
It is an allowed compile-time option to build git without iconv
support. Resulting build almost always functions correctly, and
never displays that it is missing anything, but reencode_string_len()
just never modifies its input. This gives undesirable result that
returned data or even data written into repository is incorrect
and user is not aware about it.
Show warning there is non-trivial reencoding requested. Show it only once
during program run.
