Same issue on actual ppc hardware.
The build failure is triggered by `USE="alsa -oss"`. It seems this one is actually kinda caused by pbbuttonsd-0.8.1a-fno-common.patch: it was an attempt to fix bug 771093, but it was erroneous by itself...
There is a PR long due for a review regards this bug: https://github.com/gentoo/gentoo/pull/35160
