Remove a warning from symtab.c
When building symtab.c, I get:
../../binutils-gdb/gdb/language.h: In function ‘void print_symbol_info(search_domain, symbol*, int, const char*)’:
../../binutils-gdb/gdb/language.h:738:20: warning: ‘*((void*)& l +4)’ may be used uninitialized in this function [-Wmaybe-uninitialized]
set_language (m_lang);
~~~~~~~~~~~~~^~~~~~~~
../../binutils-gdb/gdb/symtab.c:4613:41: note: ‘*((void*)& l +4)’ was declared here
scoped_switch_to_sym_language_if_auto l (sym);
^
This is another instance of the std::optional problem, see
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=80635.
However, it seemed straightforward and inexpensive to me to silence
this one, which is what this patch does.
