I'd like to understand why it behaves like this with your setup. I'm
using a 64-bit OS too (Debian Testing) but the libs go to /usr/lib as
expected.

Could you pastebin the full log of libimxvpuapi build, your buildroot
configuration as well as you 'env'?

Ok, I'll do that once I understand the difference which requires this
libdir argument.

Does a basic gstreamer pipeline work?
# gst-launch-1.0 videotestsrc ! imxeglvivsink

If not there's no wonder qt5 doesn't like it. I haven't tried qt5 but
I'm sure the gstreamer imxeglvivsink does work.

In case you've enabled BR2_PACKAGE_KERNEL_MODULE_IMX_GPU_VIV, you
might need to load the Galcore module manually in case you don't have
eudev for instance:
# insmod /lib/modules/3.14.28/extra/galcore.ko
