ginac & cln: fix cln 1.3.4, update ginac 1.6.5, add ginac 1.6.7. (#559)

sci-libs/cln:

* REQUIRES_devel was set to libcln$secondaryArchSuffix instead of
  cln$secondaryArchSuffix, therefore preventing both the installation
  of cln_devel and its use in chrooted builds of ginac.
* Drop the recipe for version 1.3.2 (which was really old.)
* Change cmd:gcc to cmd:g++ in BUILD_PREREQUIRES.
* On x86_gcc2 using x86 as secondary arch, install pi in bin/ instead
  of bin/x86/.
* Do not use $portVersion as version of lib:libcln. Instead, use the
  libs' real version. This change is safe since the only package wich
  needs libcln is ginac and it is being updated in this very commit.

sci-mathematics/ginac:

* Fix versioned dependency on libcln for ginac-1.6.5.
* On x86_gcc2 using x86 2nd arch, do not install runtimes in bin/x86/
  but in bin/.
* Add ginac-1.6.7.

+SUMMARY="A C++ library to combine symbolic manipulation with numeric computations"
+DESCRIPTION="GiNaC (which is a recursive acronym for GiNaC is Not a CAS) was \
+specifically developed to replace the Maple CAS as an engine for xloops. It is \
+a C++ library and attempts to bring the features of a typical CAS to the C++ \
+language itself. By doing that, it enables symbolic manipulation to be used in \
+existing numeric software written in C++."
