I agree with the basic idea (the big alignments also always annoy
me when I look at disassembly), but I think your CONFIG options
are far too complicated. I don't think anybody will go as far as
to tune loops vs function calls.
I would just do a single CONFIG_NO_ALIGNMENTS that sets everything to
1, that should be enough.
