Can we please find terms that describe that "old" and "new" mean and
use those instead?  "new" will eventually be old news too.
We did that mistake with "--enable-new-dtags", let's not repeat it.

For example:

 --compress-debug-sections=[none|zlib|zlib-gnu|zlib-shf-compressed]
 --compress-debug-sections=[none|zlib|zlib-gnu|zlib-shf]
 --compress-debug-sections=[none|zlib|zlib-gnu|zlib-gabi]

or even:

 --compress-debug-sections=[none|zlib|zlib-v1|zlib-v2]
