	.section	FOO_SECTION, "a"
	.align		SIZEOF_POINTER
	.{,x}word	POINTER
	.previous

Where FOO_SECTION is your special section name, SIZEOF_POINTER is
sizeof(void *), and POINTER is the pointer you want to add to the
section.

You have to also pick .word vs. .xword, or whatever the appropriate
sized pointer mnenomic is for a given architecture.  I know .word
works for 32-bit sparc, and .xword works for 64-bit sparc.
