Alexey Neyman cc6b7fad46 Retire obsoleted milestones
... and the code dependent on them, after the latest wave of obsolete
package removals. This concludes the glorious history of the original
uClibc (non-NG) with lots of kludges removed.

There was a choice here, whether to call the resulting libc "uClibc" or
"uClibc-ng". I opted in favor of giving uClibc-ng the recognition it
deserves, although it had some ripple effect in the ct-ng code.
