title: *** recipe commences before first target. Stop
body: <p>I just download the android open source project and tried to build it with make the I receive the message:</p>
  
  <pre><code>build/core/prebuilt.mk:91: *** recipe commences before first target.  Stop.
  </code></pre>
  
  <p>Here is the corresponding make file snippet (The first line here being line number 89):</p>
  
  <pre><code>ifneq ($(prebuilt_module_is_a_library),)
    ifneq ($(LOCAL_IS_HOST_MODULE),)
      $(transform-host-ranlib-copy-hack)
    else
      $(transform-ranlib-copy-hack)
    endif
  endif
  </code></pre>
  
  <p>I am not sure what's wrong with this make file? The preceding white space on line 91 is a tab.</p>
