The patch lists gcc as toplevel dir instead of libgfortran...

No worries, that was easily fixed.

I've moved the previous libgfortran dirs (32 and 64-bit) aside on both
sparc and x86, the ran make -jN configure-target-libgfortran
all-target-libgfortran.

On x86 (-j48), the build worked just fine, on sparc (-j64) I now get the
same error I had on x86 before (while compiling runtime/bounds.c,
libgfortran.h doesn't find GFC_(REAL|COMPLEX)_[48] definitions),
apparently only in the sparcv9 multilib.  Rerunning the make
all-target-libgfortran succeeds, though.

Really strange.  If kinds.h were missing completely at that point, I'd
expect gcc message to that effect, that's why I suspected the header
being incomplete instead.=
