[commit] Fix a testsuite FAIL for bfin ld

[Jie Zhang]

This patch fixes

FAIL: Weak symbols in dynamic objects 1 (main test)

for bfin-linux-uclibc-ld.

It removes empty .rel.plt, .plt and .dynbss sections. The code to remove 
those empty sections is there but only when dynamic_sections_created. 
Those sections might also be created in _bfin_create_got_section without 
setting dynamic_sections_created. So I just move the code out of guard 
of dynamic_sections_created. I also found there are two pieces of code 
to remove empty .rel.plt section. I just remove one of them with this patch.

Committed on HEAD and binutils-2_20-branch.
