This page describes the process of creating ILP32 support for LEAP.
* I downloaded gcc-4.9.2. I got mine from http://arm.koji.fedoraproject.org/koji/buildinfo?buildID=255322.
* I created a scratch build for that rpm, which is accessible here: http://blue/kojifiles/work/tasks/4937/74937/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.
