The same issue happens when I build riscv32-linux target:
  ./configure --target=riscv32-linux --with-platform=efi --enable-grub-mkfont 
--prefix=...

I use compiler from here:
  
http://mirrors.kernel.org/pub/tools/crosstool/files/bin/x86_64/8.1.0/x86_64-gcc-8.1.0-nolibc-riscv32-linux.tar.xz

Hmmm... Last week it built correctly. Do we use latest Gnulib from master?
Should not we use specific tag/commit which works for us?
