[developers] compiling fftb

[Alexandre Rademaker]

Hi Woodley,

Once I follow the proper order for compile the dependencies (liba, libace, libtsdb, fftb), I got everything to work at Linux. But no success o Mac OS yet!! :-( 

Any direction?

I found that gcc-9 is the gcc installed from brew

$ gcc-9 --version

These where my changes in the Makefile but I could not compile. 

$ svn diff Makefile
