This is a follow-up on bug 43810, as requested by comment 18:
The problem is not fixed yet, we see it when trying to enable --enable-target-optspace for the Poky / Yocto builds, for details please see comment 19:
The original bug report referred to a powerpc-eabispe target only, but we see this with other powerpc confiugrations as well (Ilya's build was for a plain vanilla ppc603e system).
See also bug 45053; sorry I missed that.
