patch: win32 linker bug workaround for .rdata$* section

[Mumit Khan]

Using just .rdata$* (grouped) sections in the C++ front-end tweaks a
linker bug, so I suggest disabling it for now (GCC currently doesn't 
use .rdata, rather puts read-only data in the .text section). When GCC 
starts using .rdata section, and hence defines READONLY_DATA_SECTION, 
this will then turn on as well.

	* config/i386/winnt.c (i386_pe_unique_section): Don't use .rdata
	section unless READONLY_DATA_SECTION is already defined. Currently
	using .rdata$* grouped sections tweaks a linker bug.
