Could you please change this so we have a commonly defined HAVE_BROKEN_RODATA
symbol. Then arch's that have broken RO data can select this symbol.
If we experience tomorrow that sparc have the same issue then with
this patch sparc has to create a local definition of this symbol.

This allows you to add some comments of the usage of this symbol
in a common place too.

Sam
