This happens at the last step of the required upgrade sequence (emerge @world): =============================================================================== If not already done, * Use gcc-config to select gcc-6.4.0 or later as system compiler * Re-source /etc/profile: . /etc/profile * Re-emerge libtool emerge -1 sys-devel/libtool Then, * Select the new profile with eselect * Re-emerge, in this sequence, gcc, binutils, and glibc emerge -1 sys-devel/gcc:6.4.0 emerge -1 sys-devel/binutils emerge -1 sys-libs/glibc * Rebuild your entire system emerge -e @world Switching the profile from 13.0 to 17.0 modifies the settings of GCC 6 to generate PIE executables by default; thus, you need to do the rebuilds even if you have already used GCC 6 beforehand. If you do not follow these steps you may get spurious build failures when the linker tries unsuccessfully to combine non-PIE and PIE code.
The Qt4 versiones emerges perfectly fine, though.
Hm yes, try a rebuild in the right order, this should help, see https://forums.gentoo.org/viewtopic-p-8159812.html#8159812
cheers mate, that does it, We can close this.
