Patches to fix ld's abort on xtensa

Also while there, fix the naming (some patches ended up with two sequence numbers somehow).

+Subject: [PATCH] xtensa: fix relaxation of undefined weak references in
+ shared objects
+
+The change c451bb34ae8b ("xtensa: don't emit dynamic relocation for weak
+undefined symbol") didn't properly handle shrinking of relocation
+sections due to coalescing of references to a dynamic undefined weak
+symbol in a shared object, which resulted in the following assertion
+failure in ld when linking uClibc-ng libthread_db for xtensa:
+
+  BFD (GNU Binutils) 2.31 internal error, aborting at elf32-xtensa.c:3269
+  in elf_xtensa_finish_dynamic_sections
+
+Shrink dynamic relocations section for dynamic undefined weak symbols
+when linking a shared object.
+
+bfd/
+2018-07-23  Max Filippov  <jcmvbkbc@gmail.com>
+
+	* elf32-xtensa.c (shrink_dynamic_reloc_sections): Shrink dynamic
+	relocations section for dynamic undefined weak symbols when
+	linking a shared object.

+Subject: [PATCH] xtensa: move dynamic relocations sections consistency
+ check
+
+The function elf_xtensa_finish_dynamic_sections checks that sizes of
+sections .rela.dyn and .rela.plt match number of corresponding relocation
+records, but the check is only done when .rela.plt is non-empty, so, e.g.
+it is never run for the static PIE.
+Rearrange the test so that .rela.dyn and .rela.plt are checked always.

+	* elf32-xtensa.c (elf_xtensa_finish_dynamic_sections): Move
+	relocation sections consistency check to always check both
+	.rela.dyn and .rela.plt when they exist. Rearrange variable
+	definition and assignment places.
