As already described in PR ada/18217, while building gnattools gnat1 gets a
bus error compiling makegpr.adb:

$ ../../xgcc -c -I./ -I../rts -I. -I/vol/gnu/src/gcc/gcc-dist/gcc/ada -B../../ -O2 -g -O2 -gnatpg -gnata -I- /vol/gnu/src/gcc/gcc-dist/gcc/ada/makegpr.adb

The file compiles without problems at -O0.  With this change and the
workaround from PR ada/18217, I was able to finish a C and Ada bootstrap.

make check currently running.
