Looking good but needs a few more patches, and you need to run the
full binutils testsuite.

grep obj_adjust_symtab says you have a tweak to make to config/tc-arm.c
egrep '(group section|GROUP)' will hit a few more testcases in
gas/testsuite/gas/ia64/, binutils/testsuite/binutils-all/, and
ld/testsuite/ld-elf/
