Ah.... I got what you mean.
It's something like:

--- a/meta/recipes-core/meta/buildtools-tarball.bb
+++ b/meta/recipes-core/meta/buildtools-tarball.bb
@@ -59,7 +59,7 @@ create_sdk_files_append () {
script=${1:-${SDK_OUTPUT}/${SDKPATH}/environment-setup-${SDK_SYS}}
         touch $script
         echo 'export PATH=${SDKPATHNATIVE}${bindir_nativesdk}:$PATH' >> 
$script
-       echo 'export OECORE_NATIVE_SYSROOT="${SDKPATHNATIVE}"' >> $script
+       echo '#OECORE_NATIVE_SYSROOT="${SDKPATHNATIVE}"' >> $script

         toolchain_create_sdk_version 
${SDK_OUTPUT}/${SDKPATH}/version-${SDK_SYS}
  }

I'll test this and send out a V2 if it works.

Thanks,
Chen Qi
