More portability.

 - The location of openssl development files got customizable.
 - The location of iconv development files got customizable.
 - Pass $TAR down to t5000 test so that the user can override with
   'gmake TAR=gtar'.
 - Solaris 'bc' does not seem to grok "define abs()".  There is no
   reason to use bc there -- expr would do.
