linux-user is failing to compile on Fedora 43:
../linux-user/strace.c:57:66: error: enum constant in boolean context
[-Werror=int-in-bool-context]
57 | #define FLAG_BASIC(V, M, N) { V, M | QEMU_BUILD_BUG_ON_ZERO(!(M)),
N }
The warning does not seem to useful and we could even disable it, but
the workaround is simple in this case.
