[Bug ada/16442] Crossbuilding the Ada RTS fails

I compiled a native 3.4.2 (CVS as of a day or two ago) for the host compiler.
This works even less well, dying during the 'make' portion of compiling the
cross-compiler:

mkdir -p ada/bldtools
cp -p /home/willy/gcc/gcc-3.4/gcc/ada/sinfo.ads
/home/willy/gcc/gcc-3.4/gcc/ada/nmake.adt
/home/willy/gcc/gcc-3.4/gcc/ada/xnmake.adb ada/bldtools
(cd ada/bldtools; gnatmake -q xnmake ; ./xnmake -b ../nmake.adb )
make[1]: *** [ada/nmake.adb] Error 139

$ gnatmake xnmake 
gnatmake: "xnmake" up to date.
$ ./xnmake -s ../nmake.ads 
Segmentation fault
$ gdb ./xnmake
GNU gdb 6.1-debian
(gdb) set args -s ../nmake.ads 
(gdb) run

I double-checked that the gnatlink/gnatmake/gnatbind/gcc in my path are coming
from the new compiler:

gcc -v -c xnmake.adb
