Probably worth mentioning that I had this error once: C compiler cannot create executables. and the solution for me was removing the -fstack-protector-strong from CFLAGS So maybe it's something similar for you, you may want to remove some from CFLAGS. I am unsure if I misspelled that flag initially and that was the actual cause, because later on using -fstack-protector-all instead, just worked.
Mh... I haven't set "-fstack*" in my CFLAGS, also the ebuild's do_filter_flags version has # xgcc isnt patched with propolice filter-flags -fstack-protector-all filter-flags -fno-stack-protector-all filter-flags -fstack-protector filter-flags -fno-stack-protector But I tried something: CFLAGS="-march=i686" emerge -a1 sys-libs/libstdc++-v3 produces errors like [...] /var/tmp/portage/sys-libs/libstdc++-v3-3.3.6-r1/work/build/gcc/xgcc -shared-libgcc -B/var/tmp/portage/sys-libs/libstdc++-v3-3.3.6-r1/work/build/gcc/ -nostdinc++ -L/var/tmp/portage/sys-libs/l ibstdc++-v3-3.3.6-r1/work/build/x86_64-pc-linux-gnu/32/libstdc++-v3/src -L/var/tmp/portage/sys-libs/libstdc++-v3-3.3.6-r1/work/build/x86_64-pc-linux-gnu/32/libstdc++-v3/src/.libs -B/usr/x86_ 64-pc-linux-gnu/bin/ -B/usr/x86_64-pc-linux-gnu/lib/ -isystem /usr/x86_64-pc-linux-gnu/include -m32 -I/var/tmp/portage/sys-libs/libstdc++-v3-3.3.6-r1/work/gcc-3.3.6/libstdc++-v3/../gcc -I/va r/tmp/portage/sys-libs/libstdc++-v3-3.3.6-r1/work/gcc-3.3.6/libstdc++-v3/../include -I/var/tmp/portage/sys-libs/libstdc++-v3-3.3.6-r1/work/build/x86_64-pc-linux-gnu/32/libstdc++-v3/include/x 86_64-pc-linux-gnu -I/var/tmp/portage/sys-libs/libstdc++-v3-3.3.6-r1/work/build/x86_64-pc-linux-gnu/32/libstdc++-v3/include -I/var/tmp/portage/sys-libs/libstdc++-v3-3.3.6-r1/work/gcc-3.3.6/l ibstdc++-v3/libsupc++ -O2 -pipe -march=core-avx-i -mno-movbe -mno-abm -mno-lwp -mno-fma -mno-fma4 -mno-xop -mno-bmi -mno-bmi2 -mno-tbm -mno-avx2 -mno-lzcnt -D_GNU_SOURCE -m32 -fno-implicit-t emplates -Wall -Wno-format -W -Wwrite-strings -fdiagnostics-show-location=once -ffunction-sections -fdata-sections -c /var/tmp/portage/sys-libs/libstdc++-v3-3.3.6-r1/work/gcc-3.3.6/libstdc++ -v3/libsupc++/del_opv.cc -o del_opv.o cc1plus: error: invalid option `no-movbe' cc1plus: error: invalid option `no-abm' cc1plus: error: invalid option `no-lwp' cc1plus: error: invalid option `no-fma' cc1plus: error: invalid option `no-fma4' cc1plus: error: invalid option `no-xop' cc1plus: error: invalid option `no-bmi' cc1plus: error: invalid option `no-bmi2' cc1plus: error: invalid option `no-tbm' cc1plus: error: invalid option `no-avx2' cc1plus: error: invalid option `no-lzcnt' cc1plus: error: bad value (core-avx-i) for -march= switch cc1plus: error: bad value (core-avx-i) for -mcpu= switch Makefile:436: recipe for target 'del_opv.lo' failed [...] So for me it looks like the internally used compiler doesn't support my march "core-avx-i" but detects it for some reason (...so the package is also ignoring my CFLAGS).
My bad, when overwriting CFLAGS via command line, I also have to overwrite CXXFLAGS ;) So builidng with CFLAGS="-march=x86-64" CXXFLAGS="${CFLAGS}" emerge -a1 sys-libs/libstdc++-v3 works! So, one of my "-mno-*" flags are causing the problem: -mno-movbe -mno-abm -mno-lwp -mno-fma -mno-fma4 -mno-xop -mno-bmi -mno-bmi2 -mno-tbm -mno-avx2 -mno-lzcnt ...I tested each one and whenever I had set an "-mno-*" flag, the build failed with the initial error. That's why I am suggesting the following fix for the ebuild to fix this bug: --- /usr/portage/sys-libs/libstdc++-v3/libstdc++-v3-3.3.6-r1.ebuild.old 2015-01-06 21:11:20.000000000 +0100 +++ /usr/portage/sys-libs/libstdc++-v3/libstdc++-v3-3.3.6-r1.ebuild 2015-01-06 21:12:14.000000000 +0100 @@ -101,6 +101,9 @@ # Bug #442784 filter-flags '-W*' + # Bug #531680 + filter-flags '-mno-*' + filter-flags -frecord-gcc-switches # ...sure, why not? Thank you EmanueL for the hint regarding the CFLAGS...
I was originally planning to move downgrade_arch_flags() from toolchain.eclass into toolchain-funcs so libstdc++-v3 could also use it but I never got around to it. It should probably be expanded a bit to include the -f flags from do_filter_flags().

I had this exact failure. Testing sys-libs/libstdc++-v3-3.3.6-r2 seems to fix it with its CFLAG stripping.
