    classes/externalsrc: delete symlinks at start of do_buildclean
    
    To help users find the work and log directories (especially within the
    eSDK) we create symlinks to these from the source tree. However during
    do_buildclean we call "make clean", and some project Makefiles which
    delete something like "*/*/lib" which will match files underneath the
    oe-workdir symlink and fail. do_buildclean is called from do_clean which
    is in turn called by devtool reset by default, and thus devtool reset is
    blocked. An example of a recipe where this is visible is the openssl-qat
    recipe in meta-intel.
    
    In order to fix this, delete the symlinks at the start of do_buildclean
    since we shouldn't need them at that point anyway, and thus make clean
    won't be able to trip over them.
    
    Fixes [YOCTO #11036].
