On x86-64 Fedora 29, I tried to build a mingw-hosted gdb that targets
ppc-linux. You can do this with:
../binutils-gdb/configure --host=i686-w64-mingw32 --target=ppc-linux \
--disable-{binutils,gas,gold,gprof,ld}
The build failed with these errors in libctf:

This patch fixes the actual errors in here. I did not try to fix the
printf warnings, though I think someone ought to.
Ok?
