Yes.  I agree ***during the build to hardcode it*** but not to add
dependency to dpkg-dev to decide it under ***normal client run time***.
(I think your proposed patch does not list dpkg-dev as dependency which
I think is bug for your code.)

Also, I question the rationale for your proposed patch which has
dpkg-architecture run on execution time during X start up code.  Your
actual X client program under multiarch may be running under a different
arch and requesting different arch libraries.

In conclusion, your patch to the ibus-1.4.0/debian/xinput/ibus file is
essentially reverted but everything else looked good.

As for the possible issues raised by you, we can not do much with the
current design of X start up code exporting some variables.  Whoever
wishes to have usable multiarch under X with input method supported for
all, they have to install them all.  This awkward situation comes from
fundamental issues of this multiarch system design.  It does not give
arch specific /etc .

The only extra fixes I can think of are if clause.  Since * may match
many binaries, we need to make script more robust like what I fix this
problem using while loop just like im-config

Thanks for your help.  Now I am a bit more up-to-date with multiarch.

Aron,

I listen to you. I will not touch im-config on this issue.  (I still
have to fix fcitx description and add po support for messages.)
