title: "CROSS_COMPILE_ARM32 not defined or empty" while rebuilding Android Kernel
body: <p>I'm trying to rebuild Kernel for Sony XZ based on Android Pie, but there is a error occuring like below. Message says " CROSS_COMPILE_ARM32 not defined or empty, the compat vDSO will not be built", it means I have to find 32-bit toolchains for compiling compat vDSO supported in Android Pie and set CROSS_COMPILE_ARM32 to an appropriate value. But I haven't yet found that toolchains so far. Can anybody help me?</p>
  
  <pre><code>arch/arm64/Makefile:83: *** CROSS_COMPILE_ARM32 not defined or empty, the compat vDSO will not be built.  Stop.
  </code></pre>
  
  <p>Thank All !</p>
