Qt-5.5.0 announce support[1] for both gstreamer-0.10 & gstreamer-1.0.
Also note that gstreamer-0.10 is still the Qt default version in case
both are present.

You probably missed that qt5base use host pkg-config to detect gstreamer
version. As autobuild chroot environment have neither of them they both
fail at qt5multimedia install time.
I already report a bug[2] but I was not able to fix it (running out of
time). Will Wagner proposed a solution[3] to that issue but he did not
spin it into Buildroot and Qt patches yet.
