Another builder. :)  Randomly picking xtensa-elf, you're configuring
as

+ ../../gcc/configure --disable-analyzer --with-system-libunwind
--with-newlib --without-headers --disable-threads --disable-shared
--enable-languages=c,c++
--prefix=/home/jlaw/jenkins/workspace/xtensa-elf/xtensa-elf-obj/gcc/../../xtensa-elf-installed
--target=xtensa-elf

I guess the main difference that lets my builds fail might be
--enable-languages=all (vs. c,c++ in your case.)

Maybe you'd give that a try? (...and I'll trigger a build with just
c,c++ on my builder.)
