Subject: [PATCH] tools: conditionally disable python libfdt wrapper

Not all host systems want the default swig to be
used when building the tools.  Allow for the
disabling of the wrapper to enable cross-compiling
of the tools on a host system with swig.

Upsteam submission for RFC:
https://lists.denx.de/pipermail/u-boot/2017-May/289520.html
