    [gdb/build] Fix build breaker in language.c with gcc 7.5.0
    
    When building gdb on openSUSE Leap 15.3, using gcc 7.5.0, I run into:
    ...
    gdb/language.c: In constructor ‘constexpr language_gdbarch::language_gdbarch()’:
    gdb/language.c:921:8: error: use of deleted function \
      ‘language_arch_info::language_arch_info(const language_arch_info&)’
     struct language_gdbarch
            ^~~~~~~~~~~~~~~~
    In file included from gdbsupport/common-defs.h:104:0,
                     from gdb/defs.h:28,
                     from gdb/language.c:31:
    gdb/language.h:95:28: note: declared here
       DISABLE_COPY_AND_ASSIGN (language_arch_info);
                                ^
    include/ansidecl.h:342:3: note: in definition of macro \
      ‘DISABLE_COPY_AND_ASSIGN’
       TYPE (const TYPE&) = delete;   \
       ^~~~
    gdb/language.c: In function ‘language_gdbarch* get_language_gdbarch(gdbarch*)’:
    gdb/language.c:936:22: note: synthesized method ‘constexpr \
      language_gdbarch::language_gdbarch()’ first required here
           l = new struct language_gdbarch;
                          ^~~~~~~~~~~~~~~~
    ...
    
    This seems to be fixed by this change in the struct language_gdbarch
    definition:
    ...
    -  struct language_arch_info arch_info[nr_languages] {};
    +  struct language_arch_info arch_info[nr_languages];
    ...
    
    Tested on x86_64-linux.
