title: arm-linux-gcc vs arm-elf-gcc
body: <p>I am looking at uClinux system that builds the kernel with arm-linux-xxx, but builds the user apps with arm-elf-xxx.</p>
  
  <p>If the apps are intended to run on linux, wouldn't it be better to build everything with arm-linux-xxx ?</p>
  
  <p>Where does one set that option in the overall uClinux build config?</p>
