Buildfarm member whelk reports for 32-bit Windows.

https://buildfarm.postgresql.org/cgi-bin/show_history.pl?nm=whelk&br=HEAD

https://buildfarm.postgresql.org/cgi-bin/show_history.pl?nm=whelk&br=REL_12_STABLE

It says it uses Microsoft Visual C++ 2010 .

I don't see any other members building for 32-bit. But it should work
and as you say, nothing's been discussed about removing it.
