I assume you mean at the same time. With the current buildsystem the answer is no. The main reason is that several packages are dependant on others and use each others symbols. In theory packages that that always compile to the same binaries could be compiled once and saved for later builds for other receivers, thus saving time, but I do not know of a toolchain that does this. The often used OpenEmbedded also builds for one receiver at the time, but retains the build result of previous built other models. The buildsystem does not do this. The solution I use is setting up a build environment per receiver model.
