  /* Set the section VMA values.  We force the .sdata and .sbss
     sections to the end to ensure that their VMA addresses are close
     together so that the GP register can address both of them.  We
     put the .bss section after the .sbss section.

     Also, for the Alpha, we must sort the sections, to make sure they
     appear in the output file in the correct order.  (Actually, maybe
     this is a job for BFD.  But the VMAs computed would be out of
     whack if we computed them given our initial, random ordering.
     It's possible that that wouldn't break things; I could do some
     experimenting sometime and find out.

     This output ordering of sections is magic, on the Alpha, at
     least.  The .lita section must come before .lit8 and .lit4,
     otherwise the OSF/1 linker may silently trash the .lit{4,8}
     section contents.  Also, .text must preceed .rdata.  These differ
     from the order described in some parts of the DEC OSF/1 Assembly
     Language Programmer's Guide, but that order doesn't seem to work
     with their linker.

     I don't know if section ordering on the MIPS is important.  */
