When compiling at -Og:
boot.c: In function 'efi_start':
boot.c:1339:9: error: 'argc' may be used uninitialized in this function
[-Werror=maybe-uninitialized]
1339 | efi_arch_handle_cmdline(argc ? *argv : NULL, options, name.s);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
although this appears to be limited to the ARM build only. It also seems to
be bogus, because it is immediately preceding by a read of argc which doesn't
yield a diagnostic.
