I tried this:
CFLAGS="-c99 -Wlp64 -Wnowarn=734 -I/usr/local-ssl3.0/include -I/usr/coreutils/include" \
  LDFLAGS="-Wlp64 -L/usr/local-ssl3.0/lib64 -L/usr/local-ssl3.0/lib -L/usr/coreutils/lib" \
 ./configure --prefix=/usr/local-ssl3.0 --bindir=/usr/local-ssl3.0/bin64 --disable-iconv \
 --disable-locale --disable-md2man --disable-xxhash --disable-lz4 --disable-zstd

Configure still reports: <snipped>
checking for library containing iconv_open... none required
checking for library containing libiconv_open... -liconv
checking for iconv declaration... 
         extern size_t iconv (iconv_t cd, char * *inbuf, size_t *inbytesleft, char * *outbuf, size_t *outbytesleft);

and uses it if the declaration exists even if disabled. The issue is that libiconv.so is 32-bit and will
not link with rsync for 64-bit.
