We can revert the change.  But the reason for it is tar preserves hard links,
while cp does not.

So if a directory being copied contain foo, foo1, foo2, and foo3  all hardlinks
of each other, they will end up still being hard links of each other on the
target side.

I previously went through the classes and updated almost all cases of CP to the
tar method.  (Obviously without the %d typo...)  This reduced over 200MB from
the eglibc build.. (mostly in locale info)
