Which seems like a good argument for default_binds_local_p and
others using a "pic" function parameter instead of grabbing the global
flag_pic. This would allow -fpic/-fPIC to affect targetm.binds_local_p
while not affecting the other functions.
For instance, rs6000_override_options could reset the GCC global
flag_pic to zero while remembering the original value privately and then
using that value to affect binds_local_p.
These uses of flag_pic seem like orthogonal decisions to me and
ports should have finer-grained control only available if binds_local_p
and select_section accept arguments.
