I have made several test, with or without the define 
"DEFAULT_THUMB_ADR_SETS_INTERWORKING",
but my test are always fails (no boot of my kernel).
The only thing I seen it's working are to made a modification on the 
kernel following the tread: https://patchwork.kernel.org/patch/10072631/.
For binutils, actually I have some doubt I have made a basic test to 
comment the part of code on do_adr and do_adrl for thumb part and I always
generate the same code which doesn't boot.

Thanks

Christophe
