Terminology maybe, but I thought the problem was that they were created with 
links to the Qt libraries being compiled, but executed using the Qt libraries at 
the RPATH location that ldd shows, or whatever other version ld.so finds.

Not to kick in open doors but there's another approach: build dedicated versions 
of the host tools needed during the build that only work with the libraries from 
the build directory. You could relink them before installing. But I presume that 
a cross-build will have to build dedicated versions anyway as the installable 
versions built for the target system won't run, so it might actually reduce 
complexity to use dedicated versions for native builds too, no?

Too late to check now :)
Is uic used during the build? If it is it was clearly not "suffering from this"!
