We currently require at least GCC 7.4 or Clang 6.0 for compiling QEMU. GCC has __builtin_mul_overflow since version 5 already, and Clang 6.0 also provides this built-in function (see its documentation on this page: https://releases.llvm.org/6.0.0/tools/clang/docs/LanguageExtensions.html ). So we can simplify the #if statement here. Signed-off-by: Thomas Huth <thuth@redhat.com>
