Hi all,

I did a tinderbox build of -HEAD as of r321376; there were failures like this (paths shortened):

    c++ -isystem ${OUTDIR}/tmp/usr/include/c++/v1 -std=c++11  -nostdinc++ -isystem ${OUTDIR}/tmp/usr/include -L${OUTDIR}/tmp/usr/lib -B${OUTDIR}/tmp/usr/lib --sysroot=${OUTDIR}/tmp -B${OUTDIR}/tmp/usr/bin  -O -pipe -G0 -EB -mabi=32 -msoft-float  -DIN_GLIBCPP_V3 -DHAVE_CONFIG_H -I${SRCDIR}/gnu/lib/libstdc++ -I${SRCDIR}/contrib/libstdc++/libsupc++ -I${SRCDIR}/contrib/gcc -I${SRCDIR}/contrib/libstdc++/include -I${SRCDIR}/contrib/gcclibs/include -I${SRCDIR}/contrib/libstdc++/include -I. -frandom-seed=RepeatabilityConsideredGood       -fno-implicit-templates -ffunction-sections -fdata-sections -Wno-deprecated   -c ${SRCDIR}/contrib/libstdc++/src/bitmap_allocator.cc -o bitmap_allocator.o
    
    cc1plus: error: unrecognized command line option "-std=c++11"
    *** [bitmap_allocator.o] Error code 1

on multiple worlds:

    [threepio:clean/base/head] rpokala% egrep -l 'stopped in .*libstdc' _.*buildworld
    _.mips.mips.buildworld
    _.mips.mips64.buildworld
    _.mips.mips64el.buildworld
    _.mips.mips64elhf.buildworld
    _.mips.mips64hf.buildworld
    _.mips.mipsel.buildworld
    _.mips.mipselhf.buildworld
    _.mips.mipshf.buildworld
    _.mips.mipsn32.buildworld
    _.powerpc.powerpc.buildworld
    _.powerpc.powerpc64.buildworld
    _.powerpc.powerpcspe.buildworld
    _.sparc64.sparc64.buildworld

No interesting build environment, just MAKEOBJDIRPREFIX and JFLAGS; clean sources and empty output directory.

Thanks,

Ravi
