well... when libstdc and other shared libs are built, are they all built
position independent? the whole idea here to make sure that we must build
position independent libstdc.so and other shared libs.  

Moreover, I have tested with the -fPIC options in 4.3.2 pre-release and the
build works OK.

also, I am getting an error from 'ld' that it can't find symbol '-lc'  .  I am
not sure if this gcc related or binutils related.  any ideas?  Please see
comment #18 for more info.

thanks
