Test 48/49 libcstdaux-1failure with Clang about dbus-broker

[dvdhrm]

This was driving me insane. This is a test that simply verifies that an expression is not constant, so it does not really care for the values of the expression. But it turns out, newer LLVM sees the non_constant_expr value being used as divisor in a previous test, and thus rightfully deduces that it cannot be 0 and thus optimizes the expression into a constant.

Now fixed in: c-util/c-stdaux@6bc45c0

This has no impact on dbus-broker, but merely affects the test-suite.

Thanks a lot!
