File help-compiler-out-by-initializing-array.patch of Package qemu.23253

Subject: help compiler out by initializing array

The pre-release gcc 11 compiler is complaining that result_raw in
bigint_test_exec is flagged as possibly being uninitialized when used
(-Werror=maybe-uninitialized). Help the compiler by initializing the
array.
