The circular dependency:
asm-offsets.c depends on asm-offsets.h and is used to generate
asm-offsets.h. So if they do not have equal timestamp all files
including asm-offsets.h (direct or indirect) will be rebuild.
Do you see same pattern as Tony where the same build sometimes goes
well, sometimes goes bad?
