Reapply change from r210245. In binutils 2.17, the code in question has
moved from ld/emultempl/elf32.em to ld/ldlang.c, so apply approximately
the same change as upstream, which has description:
* ldlang.c (lang_insert_orphan): Add __start_<section> symbol assignment
inside output section statement. Ensure only one set of symbols per
output section.
* emultempl/pe.em (gld_${EMULATION_NAME}_place_orphan): Add non-dollar
sections before dollar sections. Correct add_child list insertion.
Taken from upstream git commit 7e01d69a19a8fd079887f26853c8565da15ff340,
