Found while investigating bug 28981. This is a powerpc64 host, with 32-bit
libraries installed (Fedora 16):
[austin@gcc1-power7 wine-git]$ uname -a
Linux gcc1-power7.osuosl.org 3.1.0-0.rc9.git0.2.fc16.kh.ppc64 #1 SMP Wed Oct 12

I used:
`CFLAGS="-m32 -g -O0" ./configure && make`
to force a 32-bit build, but that fails:

looks like we're still trying to link something as 64-bit? Those fails are
32-bit though:
