+	  Set to the kernel headers version that were used to build
+	  this external toolchain.
+
+	  This is used to hide/show some packages that have strict
+	  requirements on the version of kernel headers.
+
+	  If unsure what version your toolchain is using, you can look
+	  at the value of LINUX_VERSION_CODE in linux/version.h in your
+	  toolchain. The Linux version is M.m.p, with:
+	    M = ( LINUX_VERSION_CODE >> 16 ) & 0xFF
+	    m = ( LINUX_VERSION_CODE >> 8  ) & 0xFF
+	    p = ( LINUX_VERSION_CODE >> 0  ) & 0xFF
