Subject: [PATCH next] init/main.c: make some symbols static

Make variable xbc_namebuf and function boot_config_checksum static to
fix build warnings, warnings are as follows:

init/main.c:254:6:
	warning: symbol 'xbc_namebuf' was not declared. Should it be static?
init/main.c:330:5:
	warning: symbol 'boot_config_checksum' was not declared. Should it be static?
