Yes I think everyone is seeing it, but in many distro configs bad RPATH
is only QA warning not error (that's why I was partially ignoring it
until now, concentrating on other issues).

You can see do_configure_append in qtwebkit.inc which is removing bad
rpath from qmake generated Makefile, this sometimes doesn't work, from
similar Makefile issue in qtjsondb I know that "sometimes" Makefile
generated in do_configure is regenerated later in do_compile or
do_install task, I'm not sure yet why, but that's what breaks similar
hack in qtjsondb_git.bb:do_configure_append().

Of course the real fix for both issues would be to fix .pri/.prf files
to prevent incorrect Makefile to be generated at all.
