This (and the previous fixes) was found by a knob I have in review to
switch 'make tinderbox' to using GCC toolchains when possible.  It lets
you do

'make tinderbox USE_GCC_TOOLCHAINS=yes' and it uses GCC instead of LLVM
for architectures with a GCC package.  The current patch in review at the
URL below uses GCC 6 packages.  I have a WIP branch to move to GCC9 which
adds riscv and 32-bit powerpc leaving 32-bit arm as the only architecture
without a GCC toolchain.
