Wisdom from the master!!!! :)

I have fixed this in all the linkcmds which had .rodata sections.  I did
not find .rodata sections in the following linkcmds so did nothing.  

i386ex              (Erik I. could you look into this one.)
m68k/*              (not elf)
sparc/erc32        

Ian ... please provide feedback on linker scripts.  Any hints, advice are
appreciated.  These are defintely from the "it works well enough" catefory
of development.  Over the years, I have tried to make them more consistent
but fear of breaking them has limited that.
