MFC r357873:

Merge r357864 from the clang1000-import branch:

Fix the following -Werror warning from clang 10.0.0 in sconfig:

sbin/sconfig/sconfig.c:909:5: error: misleading indentation; statement is not part of the previous 'else' [-Werror,-Wmisleading-indentation]
                                exit (-1);
                                ^
sbin/sconfig/sconfig.c:907:6: note: previous statement is here
                        } else
                          ^

The intent was to group the exit() call with the previous fprintf()
call.
