[Bug bootstrap/17427] New: powerpc-linux does not bootstrap on HEAD with --disable-checking

["drow at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

I configured with --enable-languages=c++ --disable-checking.  An
--enable-checking bootstrap succeeds.

The bootstrap fails with:

stage1/xgcc -Bstage1/
-B/scratch/dan/gcc/install-orig/powerpc-unknown-linux-gnu/bin/ -c   -g -O2
-DIN_GCC   -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes
-pedantic -Wno-long-long -Wno-variadic-macros -Wold-style-definition -Werror

    /scratch/dan/gcc/gcc/gengtype.c -o gengtype.o
/scratch/dan/gcc/gcc/gengtype.c: In function `walk_type':
/scratch/dan/gcc/gcc/gengtype.c:1905: error: unrecognizable insn:

    (nil))
/scratch/dan/gcc/gcc/gengtype.c:1905: internal compiler error: in extract_insn,

I'll attach a .i file.  This command fails:
stage1/cc1 -fpreprocessed gengtype.i -quiet -O2 -o /dev/null
