Less undefined references if add '--with-arch=i486 --with-tune=i686' to

configure.



s-atopri.o: In function `system__atomic_primitives__lock_free_read_64':

e:\test1\bd\wk\build\gcc\ada\rts/s-atopri.adb:80: undefined reference to

`__atomic_load_8'

s-atopri.o: In function `system__atomic_primitives__lock_free_try_write_64':

e:\test1\bd\wk\build\gcc\ada\rts/s-atopri.adb:188: undefined reference to

`__sync_val_compare_and_swap_8'

collect2.exe: error: ld returned 1 exit status



Full configure command line:

    --enable-languages=c,c++,ada,fortran,objc,obj-c++  \
