The "relaxed" checks above (suitable for LMA mapping into ROM scenario) means
hours of debug for other people (in my case ALLOC .bss section silently
overlapped .text section; LMA = VMA = RAM addresses).

I don't think LD "can't check .bss" is an acceptable answer; I think LD should
check (as before) ALLOC section overlap (by default or optionally).
