BAT Dictionary Fix, 1.0 branch (2018.05.01.)

It turned out that BAT's dictionary generation is/was not compatible with out-of-source builds. Making the generated library quite unusable since the build was turned such.

This is a fairly hacky fix, simplifying the dictionary generation code a lot, and adjusting the compiler options to make the build of the dictionary source generated like this, successful. Note that the patch doesn't touch the src/Makefile.am file, so a re-generation of the src/Makefile.in file would make the fixes go away...

Pinging @iconnell and @smergelm. I believe this will fix the current dictionary issues in 21.2.X. Though I have not done every possible test imaginable...
