Thomas Petazzoni 458bdf3f5f python3: optional decimal module support
This commit makes the decimal module support optional: since Python
3.3 it relies on an external library. The source code of this library
is available built-in as part of the Python sources, but in Buildroot
we generally prefer to use the external library when possible.

To achieve this, this commit adds a patch to Python that is similar to
the one we use for expat support, but this time for the
libmpdec/mpdecimal library.

As a consequence, since mpdecimal now builds properly even when
<fenv.h> is not available (on i386), this commit fixes:

Add an option to disable decimal
This patch replaces the existing --with-system-libmpdec option with a
--with-libmpdec={system,builtin,none} option, which allows to tell
Python whether we want to use the system libmpdec (already installed),
the libmpdec builtin the Python sources, or no libmpdec at all.
