I'm still seeing this issue with Qt 5.4.1 and it seems to be related
to using gold as the linker (ie adding ld-is-gold to DISTRO_FEATURES).

With Qt 5.4.x, including ld-is-gold in DISTRO_FEATURES causes uic (and
other qtbase-native binaries) to be linked with "-fuse-ld=gold", which
causes these binaries to have runtime library paths defined via
"RUNPATH" instead of "RPATH".

Since chrpath.bbclass only fixes absolute paths in "RPATH", the
absolute paths specified via "RUNPATH" in the installed binaries don't
get fixed.
