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.

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