gcc 9 when configured for fortran installs ISO_Fortran_Binding.h in

For x86_64's 32-bit architecture support, this creates a subdirectory named 'include'
inside $(libsubdir)/32 which didn't use to exist in gcc 8.
This doesn't seem correct.
I would have expected the header to exist under the target name, for example:
/usr/lib/gcc/i686-redhat-linux/9/include/ISO_Fortran_binding.h
This way it doesn't conflict with other uses.
Perhaps there is enough variability in the way you build, package, and install this
that it can break in some configurations.
I think the gcc community needs to comment on this.
