This page describes the process of creating ILP32 support for LEAP.
First, * I downloaded gcc-4.9.2. I got mine from http://arm.koji.fedoraproject.org/koji/buildinfo?buildID=255322. Then * I created a scratch buildfor that rpm, which is accessible here: http://blue/kojikojifiles/work/tasks/4937/taskinfo?taskID=74937/gcc-4.9.2-5.bb4.src.rpm.* I run "rpm -i gcc-4.9.2-5.bb4.src.rpm" to install it on AArch64 builder.* I went in the "~/rpmbuild/SPEC" directory, and run command "rpmbuild -bp gcc.spec" to get the prep stage on the rpm.
