We are the only OS putting __USE_INIT_FINI__ into gcc so I have to 
wonder why we do this. There is no code in gcc or newlib that depends on it.

There was a time when we supported m68k-coff and m68k-elf and this was 
the solution. The coff and elf systems handled static constructors 
differently.

The main point behind the __ELF__ comment was based on all our targets 
now supporting ELF. Looking more I see we have a couple of targets such 
as H8300 and SH that do not have __USE_INIT_FINI__. GCC has a comment 
about some ELF targets "use crtstuff.c to provide __CTOR_LIST__" so it 
may not be completely safe. The H8300 and SH may be such targets.

Another solution is to add __USE_INIT_FINI__ to the RTEMS cpu header 
file and remove it from gcc.

Ralf maintains the tools and it is his call on what to do.
