That's fine.  You would probably go through config/pa and replace
checks on flag_pic with flag_pie or flag_shlib, right?  I think this
will continue to work fine with my change.  If not it would be easy to
tweek.

Ok, that doesn't affect my patch.  Note GCC does not equate -D__pic__
with -fpic nor -D__PIC__ with -fPIC.  Either of -fpic or -fPIC defines
both macros on all but a couple of odd targets.  So we'd get both
macros always for pa64.
