I tried adding -fPIC to my CFLAGS for compiling this package (as can be seen above), but that fails anyway, I think because -fPIE is specified as well.

My profile is hardened/linux/amd64.

With USE="qt4 -qt5" I can get it to build, but since I'm after plasma 5, that's not really an option.

I might try a emerge -e world overnight if I can't come up with any other idea, but I tried rebuilding all qt packages with
Code:
emerge -qav1 $(equery -C l qt* | awk '{ print "="$1 }')
, and that didn't help.

This should be fixed in phonon-4.8.3-r1.
