"-m32" says "compile for 32 bits" but the libraries you are trying to
use are 64 bits ("/lib64", "x86_64"). You probably do not have the
32-bit libraries installed on the newer machine. If you install a
64-bit OS on your machine, you typically get only 64-bit libraries by
default and have to request 32-bit libraries explicitly. I don't use
SUSE on any of my machines so I can't tell you the package names to look
for, but they will typically be a variant of the 64-bit package names.
