If you absolutely must have a plain chroot command
result in the variable being set, then the simplest
thing is probably to make the qemu in your chroot be
a wrapper program that sets the environment variable
and launches the actual qemu executable.

However it's probably easier to have a simple
wrapper script in your host so you do
   chroot-raspbian bash -c "uname -rm"

and the chroot-raspbian script does the "set variable,
chroot and run command" part. (This is easier because
a wrapper inside the chroot would need to be a
statically linked C program rather than a shell script,
unless you want to mess around getting your chroot
to be able to run the host shell. A wrapper script
in the host can be a shell script without any
complication.)
