patch: fix s/case/switch/ oops in cris-sim.exp and h8300.exp

[Hans-Peter Nilsson]

There seems to have been a wholesale s/case/switch/ change some
time ago, which missed at least in some parts that the switch
argument must be guarded from arguments starting with a hyphen,
or you'd get e.g. for cris-elf "make check-binutils
'RUNTESTFLAGS=--target_board=cris-sim\{,-march=v10,-march=v32\}'":

...

This patch fixes e.g. check-binutils as per above (no changes in
results compared to my original cris-sim.exp).  GCC tests are
still in progress.

I didn't scrutinize any of the other s/case/switch/ changes.

        * baseboards/h8300.exp: Use -- before switch argument that may
        begin with "-".
        baseboards/cris-sim.exp: Ditto.
