  Log:
    mjit.c: try to fix Solaris build failure
    
    In file included from vm_core.h:87:0,
                     from mjit.c:81:
    /usr/include/signal.h:71:29: error: unknown type name 'procset_t'
     extern int sigsendset(const procset_t *, int);
                                 ^
    In file included from mjit.c:81:0:
    vm_core.h:90:16: error: '_SIGMAX' undeclared here (not in a function)
     # define NSIG (_SIGMAX + 1)      /* For QNX */
                    ^
    vm_core.h:93:19: note: in expansion of macro 'NSIG'
     #define RUBY_NSIG NSIG
    
    Errors come from vm_core.h. But obviously I don't touch those parts.
    So I guess we need something before vm_core.h.
    I included internal.h before vm_core.h so that the situation becomes the
    same as cont.c.
