Remove current directory from clang include path

I am using ArmClang and I want to remove the current directory from the include path. According to the documentation:

-I-, --include-barrier

Restrict all prior -I flags to double-quoted inclusion and remove current directory from include path

However, using both of these options I get:

ArmClang: error: '-I-' not supported, please use -iquote instead

However the -iquote option doesn't have the effect of removing the current directory form the include path, is there another way to do this?
