+scripts/kconfig/confdata.c: In function ‘conf_write’:
+scripts/kconfig/confdata.c:773:22: warning: ‘%s’ directive writing likely 7 or more bytes into a region of size between 1 and 4097 [-Wformat-overflow=]
+ sprintf(newname, "%s%s", dirname, basename);

+ ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+scripts/kconfig/confdata.c:776:23: warning: ‘.tmpconfig.’ directive writing 11 bytes into a region of size between 1 and 4097 [-Wformat-overflow=]
+ sprintf(tmpname, "%s.tmpconfig.%d", dirname, (int)getpid());
+ ^~~~~~~~~~~

+ ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Increase the size of tmpname and newname to make GCC happy.
