All that's needed in this particular case is some sort of relocation
referencing a symbol in the eh sections.  R_NONE might even do the
trick.  We'd need a new assembler pseudo-op if we want to generate
the relocs without adding rubbish in .text.

On the other hand, implementing section groups doesn't look all that
difficult.  Anybody have any ideas regarding the pseudo-op we should
use?  I'm inclined to extend .section

	.section sec_name,"axG",@progbits,group_name
	.section sec_name,"aMSG",@progbits,merge_size,group_name

perhaps the order of the merge entity size and the group should
depend on which of M or G is given first.

	.section sec_name,"aGMS",@progbits,group_name,merge_size
