arm-epoc-pe specific linker script added


Hi Guys,

  I have checked in the following patch to add an arm-epoc-pe specific
  linker script.  This was done so that the contents of the .rdata
  section could be added to the end of the .text section. which is
  required by the EPOC tools.

Cheers
	Nick

	* Makefile.am: Fix arm-epoc-pe dependencies.
	* Makefile.in: Regenerate.
	
	* emulparams/arm_epoc_pe.sh (SCRIPT_NAME): Set to epocpe.

	* scripttempl/epocpe.sc: New file: copy of pe.sc, customised for
	EPOC by placing .rdata into .text.
