The ASSERT is there because the code has been unable to find an input
file onto which in can hang a constructed section containing stubs for
interworking between ARM and THUMB code.  The function
arm_elf_set_bfd_for_interworking() in ld/emultempl/armelf.em is
responsible for making this choice.

The most like reason is that all of your input files (*/built-in.o)
are empty, or that they are all marked as non-loadable.

If you can provide a small, reproducible test case then I can
investigate further.
