It needs careful testing.  On PowerPC I run into a problem with __dso_handle 
definition.  I would like to use -msdata=sysv, but TARGET_LIBGCC_SDATA_SECTION 
is undefined in the RTEMS GCC configuration and now I get this:

the target (__dso_handle) of a R_PPC_SDAREL16 relocation is in the wrong output 
section (.data)

So probably its saver to enable this on a per target basis.
