      build: Check that the compiler and --host are consistent · 8bf9b114

      libcapsule's use with biarch containers like the Steam Runtime will
      frequently make it necessary to compile it for both x86_64 and i386.
      
      On recent Debian-derived OSs this is OK, because the toolchain is
      provided as a complete set of cross-compiler-style prefixed tools like
      i686-linux-gnu-gcc; but some OSs, like Arch Linux and very old versions
      of Debian, rely on 'gcc -m32' for their biarch support. This makes it
      very easy to do
      
          ./configure --build=x86_64-linux-gnu --host=i686-linux-gnu
      
      and accidentally produce x86_64 binaries, because there is no
      i686-linux-gnu-gcc. Give the user a hint towards the correct invocation
      in this case, which is:
      
          ./configure --build=x86_64-linux-gnu --host=i686-linux-gnu CC='gcc -m32'
      
      I've implemented this as a reusable macro, in case we want to add it to
      other projects that are likely to be cross-compiled by inexperienced
      cross-compiler users.
