TARGET_AAPCS doesn't exist. If you mean TARGET_AAPCS_BASED then this is a 
runtime expression and can't be used for preprocessor conditionals.  Either 
way I don't think we really care.  The important thing is that we only emit 
the .eabi_attribute directives on EABI based targets.

A more important consideration is that this file does not exist.

Nick: Where are you expecting elf/arm.h come from?  I can't find any evidence 
this exists outside the binutils source tree, and that is not available when 
building gcc.  The BFD_ARCH_SIZE hack is a fair indication that it isn't 
intended to be used elsewhere.
