Subject: Re: Linking against armlink produced ELF for armv6-m (thumb only) CPU

Hi,
The root cause of the issue is that the linker is assuming the wrong
defaults for an object which does not have a .ARM.attributes section.
There is no one particular build attribute causing the error, it is the
defaults ld assumes.
One workaround may be to strip all the .ARM.attributes sections out of
the objects before passing them to the linker:
arm-none-eabi-objcopy -R '.ARM.attributes' tst.o -o tst.stripped.o
Thanks,
Matt
