linker option `-version-script' vs. `-retain-symbol-file'

[Werner LEMBERG]

Ulrich Drepper, in his article on DLLs

  https://www.akkadia.org/drepper/dsohowto.pdf

(section 2.2.6), criticizes that libtool maps its `--export-symbols'
option to GNU linker option `-retain-symbol-file'.  Instead, it should
use `-version-script'.

This seems to be a valid concern.  Given that libtool already uses
`-version-script' for the Solaris linker, I wonder what are the
reasons to not use this code for the GNU linker also.
