Yes, it will.  And your handing of the exidx sections will break C++
exception-handling.

You should start with the linker scripts that we provide.  There's no
reason to write a new one from scratch, and if you do you'll likely fail
to conform to the ARM ABI.  Instead, modify the ones we provide to add
what you need.
