Rene, can you clarify why we need to use 'ar' specific to the compiler?

The problem is that this change makes gcc use the .AR variable. The 
gcc.archive action is inherited by intel-linux, but the .AR variable is not 
set for intel-linux, so static linking with intel-linux does not work.

I'd like to fix this, but first would like to fully understand the change 
you've did.

Thanks,
Volodya
