My sparc-linux-gnu builds with --enable-targets=all is failing with:

It looks like it's trying to build 32-bit sparc files during the -m64
64-bit multiarch build or similar.  Or, alternatively, doing the
32-bit multiarch build with 64-bit options.

And others have reported link failures during the testsuite on
other targets.

Is this similar to what I just got for sparc-rtems when compiling
libgcc2 with -mcpu=v8?

I can prepare a PR if you think it is different.
Rainer it seems it might be your changes?
