This was discussed before IRL, and I believe until I hear to the contrary 
that strongarm should probably still work. It just won't be perfectly 
optimal as it will fall back to the arm7tdmi multilib (the default); but 
now actually looking at GCC sources, I think it may have only a virtually 
perceptible effect even then.

Actually there is one exception that should probably not be arm-eabi which 
is the AEB target, which is arm7di and so can't work with the new tools. 
Sorry I should have mentioned that yesterday Bart. Maybe it's worth 
putting that one back, but it may not be worth even that effort since 
no-one will be using it... I think it hasn't been sold for going on 10 
years now.
