[BUILDROBOT][PATCH] Fix mmix (unused variable)


Hi!

As a leftover of r210931, an unused variable resulted in:

 g++ -c   -g -O2 -DIN_GCC  -DCROSS_DIRECTORY_STRUCTURE  -fno-exceptions -fno-rtti -fasynchronous-unwind-tables -W -Wall -Wno-narrowing -Wwrite-strings -Wcast-qual -Wmissing-format-attribute -Woverloaded-virtual -pedantic -Wno-long-long -Wno-variadic-macros -Wno-overlength-strings -Werror -fno-common  -DHAVE_CONFIG_H -I. -I. -I../../../gcc/gcc -I../../../gcc/gcc/. -I../../../gcc/gcc/../include -I../../../gcc/gcc/../libcpp/include -I/opt/cfarm/mpc/include  -I../../../gcc/gcc/../libdecnumber -I../../../gcc/gcc/../libdecnumber/dpd -I../libdecnumber -I../../../gcc/gcc/../libbacktrace    -o mmix.o -MT mmix.o -MMD -MP -MF ./.deps/mmix.TPo ../../../gcc/gcc/config/mmix/mmix.c
../../../gcc/gcc/config/mmix/mmix.c: In function âint64_t mmix_intval(const_rtx)â:
../../../gcc/gcc/config/mmix/mmix.c:2694:12: error: unused variable âretvalâ [-Werror=unused-variable]
   uint64_t retval;
            ^
cc1plus: all warnings being treated as errors
make[2]: *** [mmix.o] Error 1


(See eg.  http://toolchain.lug-owl.de/buildbot/show_build_details.php?id=305352)



Committed as obvious, fixed like this:
