Right, I think the problem that you're running into is that you also disabled 
pkg-config.

So the build without dbus headers is broken, but in order for Qt to find the 
dbus headers (and library), it needs to ask pkg-config where they are. If 
that's disabled (your case), then it looks for them in /usr/include, i.e. 
/usr/include/dbus/dbus (technically that's not correct, it searches for 
dbus/dbus.h in all the include search paths). If you run configure with -v you 
should see the dbus configure compilation test failing, because they are 
located somewhere else.

The easiest workaround is to get pkg-config to work for you. The second option 
is to cherry-pick the fixes from Gerrit that address the problem of building 
without dbus headers (they aren't needed anymore). And the third option might 
be to set CPLUS_INCLUDE_PATH to help configure and Qt find the headers. You may 
have to do the same for the libraries, in case libdbus-1.so isn't in one of 
your standard library search paths.

Oh, and the fourth option is to disable dbus with -no-dbus, but I don't know 
if your setup allows for that :)
