I can easily enough move the compare_signatures into an arm/x86 
directory, and have a default version in the code.
The problem would be for bulk lookup. The function is already duplicated 
  2 times (the l and lf version). If I remove the #ifdefs, I'll need to 
duplicate them again into 4 nearly identical versions (dense and 
sparse). The only third options I see would be some preprocessor macro 
to patch the function, but that looks even dirtier to me.
I think duplicating the code would be bad, but I can do it if you want. 
Unless you have a better solution?
