Why? The 32bit libGL then looks in /usr/lib/i486-linux-gnu/dri on amd64.
That is where the files belong under multiarch.

But then the non native arch would also always look there first and find
the wrong plugins and fail to load them. Hopefully they then would keep
searching and find the right plugin as second try but that requires
extra logic in the source. Better to search the specific dir first and
then fallback to the common dir. It is not like the extra stat() will
slow things down noticeably.
