The write bit is being set somewhere, and it almost certainly because
some writable input section is being mapped to the .rodata output
section.  Generate a map file using the -Map option, and look at all
the input sections to the .rodata output section.  Perhaps some input
section named other than .rodata* is being included in the output
section.
