Currently, combining '-mxl-multiply-high' with -mcpu=v11.0 produces the

warning: '-mxl-multiply-high' can be used only with '-mcpu=v6.00.a' or

Since strcasecmp() doesn't properly compare single-digit cpu versions with
double-digit versions, switch MICROBLAZE_VERSION_COMPARE() to use strverscmp()
instead.
* config/microblaze/microblaze.cc (MICROBLAZE_VERSION_COMPARE): Use
strverscmp() to fix bogus warnings when passing multi-digit -mcpu
versions on the command line.
But strverscmp doesn't ignore character case. ISTM that you need to
canonicalize the case first if you're going to use strverscmp.
