To limit #ifdef-ary utilize some of the CASE_*() macros we have, by providing variants expanding to (effectively) nothing (really a label, which in turn requires passing -Wno-unused-label to the compiler when build such configurations). Due to the mixture of macro and #ifdef use, the placement of some of the #ifdef-s is a little arbitrary. The resulting object file's .text is less than half the size of the original, and looks to also be compiling a little more quickly. This is meant as a first step; more parts can likely be disabled down the road.
