better sizes Re: ACE/TAO on RTEMS

[Joel Sherrill]

OK.  Now that I have worked out the kinks and gotten
the "ace_main" called from our init task, the linker
actually has to include stuff.  Here are some sizes.

bash$ sparc-rtems-size A*Test
   text	   data	    bss	    dec	    hex	filename
1246128	  14768	  39700	1300596	 13d874	ARGV_Test
1224784	  14768	  39700	1279252	 138514	Aio_Platform_Test
1223888	  14768	  39700	1278356	 138194	Atomic_Op_Test
1254512	  14960	  39700	1309172	 13f9f4	Auto_IncDec_Test

How does this look Rosimildo?  These are still just ACE.  I need
to rebuild TAO and the ORB  services to get TAO numbers.

Before the sections stuff, I was about to post a patch.  Once
I link a TAO test, I will do so.
