    databases/mysql80-server databases/mysql81-server: fix build with libc++ 18 on i386
    
    When building against libc++ 18, several iostream classes now get
    inlined into C++ binaries for efficiency. But because the mysql ports
    use -malign-double on non-powerpc architectures, this causes an ABI
    problem with libc++.so, which has not been built with that flag, at
    least on i386. This can cause segfaults during the build of the port.
    
    If it is not the architecture default, as it is on amd64, -malign-double
    should not be used without recompiling basically the entire userspace
    runtime. Quoting the gcc docs:
    
    > Warning: if you use the -malign-double switch, structures containing
    > the above types are aligned differently than the published application
    > binary interface specifications for the x86-32 and are not binary
    > compatible with structures in code compiled without that switch.
    
    Hence, remove -malign-double from CXXFLAGS for these ports.
