If you want to build 64-bit and 32-bit in the same tree without them
stomping on each other, use SEPARATE_BIN=1 (you already need to do this
for TOOLS=1 anyway).
* Removed empty nl_examples from dist.mak
* Added copyright acknowledgements and full text of licenses to binary distribution
* Fixed up the list of third-party libraries
* Moved WDL fft.c to 3rdparty
