    classes/populate_sdk_ext: reset TCLIBCAPPEND to get consistent TMPDIR
    
    populate_sdk_ext sets TMPDIR to a known static value with '/tmp' directory
    name and that name is hard coded in a few places (e.g., in
    meta-environment-extsdk.bb that writes the eSDK environment variables).
    
    Distros that do not reset TCLIBCAPPEND (poky does) end up getting
    TMPDIR = /tmp-${TCLIBCAPPEND} via defaultsetup.conf and that breaks
    the functionality in eSDK that expects everything is in /tmp.
    
    To get TMPDIR consistent, we also need to reset TCLIBCAPPEND in
    populate_sdk_ext.bbclass.
    
    Fixes: [YOCTO #11298]
