The beef of your report seems to be: I get errors from Sun ld linking
libgnat-4.4.so.  In my experience, this only happens when you re-run
make bootstrap in a completed build or re-start it after the build
failed at some point.  For some reason, the libgnat objects seem to be
rebuild without -fPIC, leading to the observed error.  Seems like a bug
in the Ada build system to me.

I don't think there is any flag day involved, this error just depends
very much on the circumstances of the build.

I simply used to remove the gcc/ada/rts{, rts_amd64} directories and a
couple of stamp files when I encountered this, though I haven't in a
long time.  Perhaps the build system error is gone now.
