Subject: misc: do not use "tar cf - |tar xf -"

Using this: tar cf - -C "/some/place" |tar xf - -C "/some/other/place"
to copy a directory to another place does not properly fail (when it does).

Using this instead: cp -av "/some/place" "/some/other/place"
makes it easy to see why and how it failed.

Impacted:
    libc/uClibc
    debug/ltrace
    tools/sstrip
    scripts/populate
