    build: Unset CDPATH to avoid problems · 41faf52b

    In some places the output of commands, which include "cd" are used.
    In case of CDPATH the new path is printed, which might not be expected.
    Disable the variable to avoid these problem.
    
    When CDPATH was set by the user to some value like "export CDPATH=."
    the git checkout done by the build system did not work anymore, the
    git cloning aborted with such an error message for example:
    ....
    Packing checkout...
    tar: /disk/fs1/tmp2/mehrtens/pon-ugw/ugw-haps/openwrt/tmp/dl/ppa-drv-1.0\n@1534240258: Cannot stat: No such file or directory
    tar: Date sample file not found
    Try 'tar --help' or 'tar --usage' for more information.
    .....
    
    To avoid this, this patch makes the build system unset CDPATH inside
    the build system, so the build system will still work even when the
    user set this variable in his local environment.
