Ada broken on i686-linux

[Arnaud Charlet]

Bootstrapping with default options or -O0 yields:

stage1/xgcc -Bstage1/ -B/home/charlet/cvs/gcc-obj/install/i686-pc-linux-gnu/bin/ -c -g -O0      -gnatpg -gnata -g -O1 -fno-inline \
>  -I- -I. -Iada -I../../gcc-head/gcc/ada ../../gcc-head/gcc/ada/a-except.adb -o ada/a-except.o
