 MacPorts 2.8.1 does not create symlink to source when {{{worksrcpath}}} is
 specified.

 This is breaking behavior from version 2.8.0. See e.g.,
 https://trac.macports.org/ticket/66690.

 The problem with the latest MacPorts version is that the {{{worksrcpath}}}
 specified by the Portfile is created as an actual directory, not a symlink
 to the untamed source contents created by the {{{extract}}} phase. This
 will be a problem with any port that specifies {{{worksrcpath}}}—I cannot
 recall why I did this for {{{cabal}}} but I believe that there was a good
 reason. See below.

 How to observe the issue. The directory {{{cabal-install-3.8.1.0}}} should
 be a symlink to {{{cabal-Cabal-v3.8.1.0}}}.
