i960 ELF use of elf32.em

[Alan Modra]

i960-elf tries to use elf32.em with a generic linker backend.  Lots of
things won't work, eg. symbol versioning.  Changing over to use the
correct file, generic.em, results in these testsuite changes:

-FAIL: ld-elf/group4
-FAIL: ld-elf/group5
-FAIL: ld-elf/group6
-FAIL: ld-elf/group7
+FAIL: ld-elf/orphan
-XPASS: ld-elf/warn2

The orphan failure isn't particularly bad, just different section
ordering to that expected by the test.

	* emulparams/elf32_i960.sh (TEMPLATE_NAME): "generic", not "elf32".
	(EXTRA_EM_FILE): Define.
