Yes, the correct way to do this is to edit the file 
gcc/config/arm/t-arm-elf and uncomment the lines

# MULTILIB_OPTIONS    += mno-thumb-interwork/mthumb-interwork
# MULTILIB_DIRNAMES   += normal interwork
# MULTILIB_EXCEPTIONS += *mapcs-26/*mthumb-interwork*

Then rebuild and reinstall your compiler.

R.
