GCC segfault (ICE) while building in qemu-user sparc64
Steps to reproduce:
1. Follow Qemu-user [documentation](https://wiki.gentoo.org/wiki/Embedded_Handbook/General/Compiling_with_qemu_user_chroot) for Sparc64
2. Attempt to build libpaper: `emerge -v app-text/libpaper-2.1.0:0/2`

Resulting compilation will fail with an internal compilation error.
Additional information:
This can be tested by trying to [compile](/uploads/ba4585ea75fa157a34bf8f3ffb64bded/H1NM.i) with `gcc -mcpu=ultrasparc -O2 -c` instead of building the entire libpaper package.
