Why not compile it directly on the 32bit box.

Compiling a 32bit prog needs 32bit libs linked into it, not 64bit.
gcc was looking at the 64bit libs and complained about them.
Probably easier to download latest, or copy over old, precompiled
32bit libs of openssl and resolver than trying to compile them too from
source as 32bit. They're usually in 32bit package repos of whatever OS.
Also easier to add -static to LDFLAGS CPPFLAGS, else
you'll probably have to copy all the compiled against 32bit libs
over to the 32bit box into whatever hiers or
into a dedicated private LD_LIBRARY_PATH dir.
Maybe the OS already has a up to date 32bit fetchmail
package binary users could manually extract and run.
That's all userland, then there's kernel ABI...
especially if crossing major kernel version nums.
Uprev direction might require kernel rebuild with
compat options, compat libs, etc. Downrev is more work.

The work involved building into old prods usually
triggers migration and a vow to keep updated.
