It is.

I added code to tell it when not to use fbreg, but i only told it not to
use fbreg in the location expression when we were outputting the
frame_base attribute.

However, it appears we don't output a frame base attribute for external
procedures, so we need to tell it it can't use if we don't have a frame
base attribute.

You just need to change when loc_descriptor is called with a second
parameter of true/1 to fix this.
