Committed: fix tls_size usage for CRIS. FRV heads-up.

[Hans-Peter Nilsson <hans-peter dot nilsson at axis dot com>]

None of my test-cases covered a non-empty .tbss...

The elf_hash_table (info)->tls_sec->size covers only the .tdata
section, so a segment size is needed, and thankfully there's a
nice pre-computed elf_hash_table (info)->tls_size to use; there
should be no references anywhere to
elf_hash_table (info)->tls_sec->size for any sane TLS
implementation.

Looks like FRV has the same bug.

Anyway, here's the fix and a test-case that shows a difference.
Committed.

bfd:
	* elf32-cris.c (cris_elf_relocate_section): Use elf_hash_table
	(info)->tls_size, not elf_hash_table (info)->tls_sec->size for
	the size of local TLS data.

ld/testsuite:
	* ld-cris/tls-tbss64.s, ld-cris/tls-e-80.d: New test.
