Proposed fix

Here is a proposed patch which detects whether the target_cpu is power10 and
target is ppc64le.  I've seen it build successfully on gcc135 (without
bootstrap) and bootstrap on gcc120  (I'm currently running a bootstrap on
gcc135).

I'm unsure whether these libgm2/configure.ac and gcc/m2/configure.ac tests =
are
sufficient - and suspect more combinations should be checked (ie the shell =
case
statements might need expanding).=
