    gdb/linespec.c: Fix -Wmaybe-uninitialized warning
    
    Although the bool want_start_sal isn't actually used without being assigned
    a value, initialize it to be false in order to prevent the following
    -Wmaybe-uninitialized warning:
    
        linespec.c: In function ‘void minsym_found(linespec_state*, objfile*, minimal_symbol*, std::vector<symtab_and_line>*)’:
        linespec.c:4150:19: warning: ‘want_start_sal’ may be used uninitialized [-Wmaybe-uninitialized]
         4150 |   if (is_function && want_start_sal)
