PowerPC64 check_relocs

Tidy the dynamic reloc handling code in check_relocs, removing
leftover comments and code from when check_relocs was called as each
object file was read in.

	* elf64-ppc.c (ppc64_elf_check_relocs): Tidy dynamic reloc
	handling code.
	(dec_dynrel_count): Do the same here.

-	  /* If we are creating a shared library, and this is a reloc
-	     against a global symbol, or a non PC relative reloc
-	     against a local symbol, then we need to copy the reloc
-	     into the shared library.  However, if we are linking with
-	     -Bsymbolic, we do not need to copy a reloc against a
-	     global symbol which is defined in an object we are
-	     including in the link (i.e., DEF_REGULAR is set).  At
-	     this point we have not seen all the input files, so it is
-	     possible that DEF_REGULAR is not set now but will be set
-	     later (it is never cleared).  In case of a weak definition,
-	     DEF_REGULAR may be cleared later by a strong definition in
-	     a shared library.  We account for that possibility below by
-	     storing information in the dyn_relocs field of the hash
-	     table entry.  A similar situation occurs when creating
-	     shared libraries and symbol visibility changes render the
-	     symbol local.

-	     If on the other hand, we are creating an executable, we
-	     may need to keep relocations for symbols satisfied by a
-	     dynamic library if we manage to avoid copy relocs for the
-	     symbol.  */
