There is a check already, it will disable the CFI directives if the section is 
made again read-only, so you'll need to invert it for x86-64.

Are you sure it's a patch against the trunk?  My pristine tree has:

/* The Sun linker doesn't merge read-only and read-write sections into
   a single read-write section so we must force all EH frame sections
   to be read-write.  */
#define DWARF2_EH_FRAME_READ_ONLY 0
