[PATCH 2/8] or1k: Fix dynamic TLS symbol flag

[Stafford Horne]

The dynamic flag used for TLS relocations was not properly being set
for some cases causing link failure.  The fix here was mostly copied
from other BFD implementations.

	* bfd/elf32-or1k.c (or1k_elf_relocate_section): Fixup dynamic
	symbol detection.
