[PATCH]: Use KEEP for some HC11/HC12 sections

Hi!

To prevent the GC to remove some HC11/HC12 special sections (vectors, startup code
and finish code), these sections must be marked with KEEP.

I've committed this patch to fix that.

	Stephane

2002-10-13  Stephane Carrez  <stcarrez@nerim.fr>

	* scripttempl/elfm68hc11.sc: Use KEEP for .vectors, .installN,
	.finiN section.
	* scripttempl/elfm68hc12.sc: Likewise.
