Essentially this change:

As far as I understand it (which isn't very far)
a) it includes ubuntu's MultiArchCross.cmake toolchain all the time
for just about every cmake project
b) semi-hardcodes qmake/moc/rcc to the system Qt path
/usr/lib/$architecturetriplet/... when env DEB_HOST_MULTIARCH is set
(which apparently is always the case when building a package on

Should be fixed as per:

The files (or rather paths set in there) are simply overridden as per
the cross compilation stuff described above. Since you want the host
architecture tooling (e.g. i386) but the qt cmake config would point
to the target tooling (e.g. arm), so it's a matter of incomplete logic
of when to force these values as the main env var is set all the time.
But I suggest you ask xnox directly about the motivation behind the
toolchain file.
