Make finished with errors


[yoichiro]

I guess the reason as like the following:

• The g_led_config is defined in the symmetria.c file.
• The error message of the building task was "undefined reference to `g_led_config'".
• Remap build server generates unique string (KB_DIR_NAME) and creates a directory using the KB_DIR_NAME under the keyboards directory. Then, each registered file is created under the KB_DIR_NAME directory.
• QMK Firmware tries finding KB_DIR_NAME.h and KB_DIR_NAME.c files with the KB_DIR_NAME.
• The KB_DIR_NAME was not symmetria. That is, the symmetria.c was not targetted of the compilation process. As the result, the g_led_config was not compiled and the linker was started. Finally. the error occurred.

This issue was fixed.
