From: Peilin Ye <peilin.ye@bytedance.com>
Recently we fixed a bug in objcopy's --only-keep-debug option for ELF
relocatables. Add a test for it.
binutils/ChangeLog:
* testsuite/binutils-all/objcopy.exp
(keep_debug_symbols_for_elf_relocatable): Test --only-keep-debug
marks non-debug output sections as NOBITS for ELF relocatables
