    x86/build: limit #include-ing by asm-offsets.c
    
    This file has a long dependencies list and asm-offsets.h, generated from
    it, has a long list of dependents. IOW if any of the former changes, all
    of the latter will be rebuilt, even if there's no actual change to the
    generated file. Therefore avoid including headers we don't actually need
    (generally or configuration dependent).
