Yes with --fix-v4bx/--fix-v4bx-interworking its possible.

Not any particular case but some versions of compiler do not pass
flags to --fix-v4bx-interworking ld.

I was thinking its more apt to describe the machine with not
supporting THUMB_INTERWORK
hmmm but I now I see that we will need it for v4/EABI support. So
better fix the compiler.
