Restructured build section. Created smaller files. Created (hidden) sub-ToCs. Added out-dated build instructions for Windows GNAT GPL flow from private README.md.

+GHDL with mcode backend build on GNU/Linux with GCC/GNAT
+########################################################
+
+On Linux, GHDL is configured by ``configure`` and build by ``make``.
+
+* First, GHDL needs to be configured. It is common to specify a ``PREFIX``
+  (installation directory like ``/usr/local`` or ``/opt/ghdl``). Without any
+  other option, ``configure`` select `mcode` as backend.
+
+* Next, ``make`` starts the compilation process.
+
+* Finally, ``make install`` installs GHDL into the installation directory
+  specified by ``PREFIX``. You may need super user privileges (``sudo ...``).
+
+
+.. rubric:: Example:
+
+.. code-block:: Bash
+   
+   cd <ghdl>
+   mkdir build
+   cd build
+   ../configure --prefix=PREFIX
+   make
+   sudo make install

+Mcode Backend

+The mcode backend is available for all supported platforms and is also the most
+simplest procedure, because it requires the least dependencies and configuration
+options.
