I linked to the FSF FAQ earlier, and I think it is clear:

http://www.gnu.org/licenses/gpl-faq.html#CanIUseGPLToolsForNF

I don't think this is a real problem in practice.  The statement on
libgcc/libgcc2.c is clear.  No part of gcc/config/arm/arm.h is copied
into libgcc2.c.  However, if you are concerned about it, I recommend
that you raise the issue with the GCC Steering Committee (by sending
an e-mail to gcc@gcc.gnu.org).
