            Bug ID: 65794
           Summary: Building crossback fails: No rule to make target
                    `auto-build.h', needed by `build/genmddeps.o'
           Product: gcc
           Version: 6.0
            Status: UNCONFIRMED
          Keywords: build
          Severity: normal
          Priority: P3
         Component: other
          Assignee: unassigned at gcc dot gnu.org
          Reporter: gjl at gcc dot gnu.org
              Host: i386-mingw32
            Target: x86_64-linux-gnu
             Build: x86_64-linux-gnu

GCC configured as:

../../gcc.gnu.org/trunk/configure --build=x86_64-linux-gnu --host=i386-mingw32
--enable-languages=c,c++ --target=x86_64-linux-gnu
--prefix=/home/georg/gnu/install/gcc-64-32-cross

with empty build and empty install directory.

Building the compiler aborts:

The system has a i386-mingw32 toolchain installed, but presumably the above
problem occurs also with other crossback configuration with 

build = target != host
