We checked it with dicska and determined that r128174 is the culprit.

The problem in nutshell: the SVN revision of last success build is appended 
at the end of WebKitBuild/Relase/.qmake.cache after the build is finished.
But _all_ makefiles depends on .qmake.cache and this dependency triggers
run qmake / regenerate makefiles _always_, because .qmake.cache is _always_
newer than any makefile.

Previously WebKitBuild/Relase/.webkit.config contained the SVN revision
which isn't dependency of any makefile. And .qmake.cache - dependency of
all makefile - wasn't updated always.

Any idea how to fix it?
