title: cross compiling for ARM in recipe
body: <p>I am trying to finish the yocto-labs tutorial for beaglebone black. In the tutorial, I am asked to write recipes for the "nInvaders" game. However, I cannot cross compile it. The tutorial says  I need to cross-compile nInvaders for ARM.</p>
  
  <p>ninvaders.inc:</p>
  
  <pre><code>SUMMARY = "Space Invader Game"
  
  HOMEPAGE = "http://ninvaders.sourceforge.net"
  SECTION = "base"
  SRC_URI = "${SOURCEFORGE_MIRROR}/ninvaders-0.1.1.tar.gz"
  
  
  SRC_URI[md5sum] = "97b2c3fb082241ab5c56ab728522622b"
  
  
  do_compile() {
      oe_runmake
  }
  
  do_install() {
      install -d ${D}${bindir}
      install -m 0644 nInvaders ${D}${bindir}
  }
  </code></pre>
  
  <p>I will be more than happy, if you help me. 
  Thank you.</p>
