#72007: xfig 3.2.9a: dependency on legacysupport and gsed can be removed

 Keywords:  haspatch     |       Port:  xfig
-------------------------+--------------------
 The portfile lists PortGroup legacysupport due to strndup(). Version
 3.2.9a does not use strndup() any longer, at least in the code. Reference
 to strndup still exists in the configure script.

 Also, the build should work now with sed from darwin, no need for gsed.

 Neither of the changes are tested.
