Currently, combining '-mxl-multiply-high' with -mcpu=v11.0 produces the
following bogus warning:
echo "int main(){}" | ./microblazeel-linux-gnu-gcc -mxl-multiply-high \
-mno-xl-soft-mul -mcpu=v11.0 -nostdlib -x c -
warning: '-mxl-multiply-high' can be used only with '-mcpu=v6.00.a' or greater
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.
