Hi H.J.
With the patch applied the new linker tests are failing if you run them with
address sanitization enabled:
Executing on host: sh -c {./ld-new -o tmpdir/main.x -z norelro
-L/work/sources/binutils/branches/2.37/ld/testsuite/ld-plugin -plugin

tmpdir/text.o --defsym __stack_chk_fail=0 --defsym printf=main --defsym
puts=main 2>&1} /dev/null ld.tmp (timeout = 300)
spawn [open ...]
