 The underlying tool defaults to non-PIC, but if invoked through the GCC 
driver it does not.  As a result the behaviour of the setup is consistent 
for Linux -- for any language, including assembly, GCC produces PIC code 
by default and non-PIC if run with the "-mno-abicalls" option.  Your 
reason for doing it differently for IRIX is not immediately clear to me, 
but if you find it important, I won't argue.

 Of course normal users (i.e. non-toolchain developers) don't run gas 
directly, so the internals of the setup (no matter how silly) are not 
interesting to them -- it's the end result they care about.
