--- Comment #7 from Richard Biener <rguenth at gcc dot gnu.org> ---
What's the failure mode?  It works fine for me with

../configure --prefix=/usr --infodir=/usr/share/info --mandir=/usr/share/man
--libdir=/usr/lib --libexecdir=/usr/lib
--enable-languages=c,c++,objc,fortran,obj-c++,ada,go --enable-checking=release
--disable-werror --with-gxx-include-dir=/usr/include/c++/7 --enable-ssp
--disable-libssp --disable-libvtv --disable-libmpx --disable-libcc1
--enable-plugin --with-bugurl=http://bugs.opensuse.org/ '--with-pkgversion=SUSE
Linux' --with-slibdir=/lib --with-system-zlib --enable-__cxa_atexit
--enable-libstdcxx-allocator=new --disable-libstdcxx-pch
--enable-version-specific-runtime-libs --with-gcc-major-version-only
--enable-linker-build-id --enable-linux-futex --enable-gnu-indirect-function
--program-suffix=-7 --without-system-libunwind --with-cpu=default32
--with-cpu-64=power4 --enable-secureplt --with-long-double-128
--build=powerpc64-suse-linux --host=powerpc64-suse-linux

and

make 'STAGE1_CFLAGS=-g -O2' 'BOOT_CFLAGS=-fmessage-length=0
-grecord-gcc-switches -O2 -D_FORTIFY_SOURCE=2 -funwind-tables
-fasynchronous-unwind-tables -g -U_FORTIFY_SOURCE' -j8 -l16

(do you use profiledbootstrap?) at r249772.

If you bisected to r249738 and can reproduce can you bisect it to one of the
individual backported PRs please?  I'll be on vacation for the next two weeks
so I'd appreciate help here.  The backport should be harmless apart from maybe
the largefile support in libgcov?
