Hi.

This is a new board file for running the testsuite with fission
but without .gdb_index.

Fission isn't generally used without .gdb_index.
I could make gdb refuse to debug fission-compiled programs that
don't have .gdb_index, but it's useful for testing, and I couldn't
think of a good enough reason to prohibit it (it's not that much
extra code to support it - OTOH it is another variation to test).

Do you see the 'rsh to host fission-no-index' when tfile.exp is run with
this board file?

No.  Thanks for checking.
I vividly remember tripping over this, but I can't repro the context.
I'll delete it, and we can always add something later should the need arise.
