I've applied to master. Note however that it in fact doesn't really
solve the problem entirely, because $(HOST_DIR)/bin is not in the PATH,
so rauc still doesn't find mksquashfs:

$ ./output/host/bin/rauc --cert demo.cert.pem --key demo.key.pem bundle output/images/t/ test.raucb
input directory: output/images/t/
output bundle: test.raucb

(rauc:17776): rauc-WARNING **: failed to create bundle: Failed to start mksquashfs: Failed to execute child process ?mksquashfs? (No such file or directory)

But mksquashfs is in output/host/bin. Perhaps rauc should also try to
find mksquashfs from the same directory as rauc, before trying a
system-wide installed one?

Or we expect people to run "rauc bundle" from a post-image script, in
which case $(HOST_DIR)/bin is in the PATH ?

Best regards,

Thomas
