Comment (by mouse07410):

 I've applied your recommendation, and, while more tests are needed, it
 looks like it works.

 In summary, the workaround that you proposed and I tested is:
 - create a new directory and put the offending library in it;
 - list that directory first in the "extra-lib-dirs:" parameter for Haskell
 utilities Cabal and Stack.

 Figuring the correct format for the above was a greater pain than
 everything else together.

 For Stack (in {{{~/.stack/config.yaml}}}) include this (I list all the
 directories I need - libiconv is in /opt/local/lib/liconv, new OpenSSL in
 /opt/local/lib, etc):
 {{{
 extra-lib-dirs: [ /opt/local/lib/liconv, /opt/local/lib, /usr/local/lib ]
 }}}

 For Cabal (in {{{~/.cabal/config}}}) include this:
 {{{
 library-vanilla: False
 executable-dynamic: True
 extra-lib-dirs: /opt/local/lib/liconv
 extra-lib-dirs: /opt/local/lib
 extra-lib-dirs: /usr/local/lib
 }}}

 Thank you for your help!

 P.S. I still think that having a {{{no-name-mangling}}} variant of the
 {{{libiconv}}} port would be a good thing.
