sh*-elf: Don't make .stack section in shared libs

[kaz Kojima]

Hi,

On sh*-elf target, now ld testcases which try to make shared libs
fail with "not enough room for program headers" error. The patch
below fixes them by avoiding to make the .stack section in shared
libs. I'll check it in to the mainline if there is no objection.

Regards,
	kaz

	* emulparams/shelf.sh (OTHER_SECTIONS): Don't include .stack
	section for shared library.
	* emulparams/shelf32.sh (OTHER_SECTIONS): Likewise.
