I gave in, grabbed an x86 distro, built libcurl in 32 bits from the CD,
and that has bypassed the whole problem. I'd be interested to hear of
anyone who has actually built in 32bits on x64 arch...I can't find any
discussion online, but then again the need to do this kind of job at all
is rare in the Linux domain.

Even if this "real cross-comp" you're talking about is the ultimate
solution, -m32 really ought to work as well!
