Fails compilation while adding multilib support to libstdc++-v3. Problem appears to be related to amd64 multilib and libsandbox. Reproducible: Always Steps to Reproduce: 1. unmask it, keyword it 2. emerge =gcc-4.0.0 3. Actual Results: Adding multilib support to Makefile in /var/tmp/portage/gcc-4.0.0/work/gcc-4.0.0/libstdc++-v3 multidirs=32 with_multisubdir= Running configure in multilib subdirs 32 pwd: /var/tmp/portage/gcc-4.0.0/work/build/x86_64-pc-linux-gnu/libstdc++-v3 Running configure in multilib subdir 32 pwd: /var/tmp/portage/gcc-4.0.0/work/build/x86_64-pc-linux-gnu mkdir 32 configure: creating cache ./config.cache checking build system type... x86_64-pc-linux-gnu checking host system type... x86_64-pc-linux-gnu checking target system type... x86_64-pc-linux-gnu checking for a BSD-compatible install... /bin/install -c checking whether build environment is sane... yes checking for gawk... gawk checking whether make sets $(MAKE)... yes checking for x86_64-pc-linux-gnu-gcc... /var/tmp/portage/gcc-4.0.0/work/build/gcc/xgcc -B/var/tmp/portage/gcc-4.0.0/work/build/gcc/ -B/usr/x86_64-pc-linux-gnu/bin/ -B/usr/x86_64-pc-linux-gnu/lib/ -isystem /usr/x86_64-pc-linux-gnu/include -isystem /usr/x86_64-pc-linux-gnu/sys-include -m32 checking for C compiler default output file name... a.out checking whether the C compiler works... configure: error: cannot run C compiled programs.
