[ Upstream commit af8bbce92044dc58e4cc039ab94ee5d470a621f5 ]
A macro placed at the end of a file with no newline causes an infinite
loop.
[Test Kconfig]
$(info,hello)
\ No newline at end of file
I realized that flex-provided input() returns 0 instead of EOF when it
reaches the end of a file.
Fixes: 104daea149 ("kconfig: reference environment variables directly and remove 'option env='")

Fix some warnings from sparce like follows:
warning: symbol '...' was not declared. Should it be static?

Valid pathnames will never exceed PATH_MAX, but these file names
are unsanitized and can cause buffer overflow if set incorrectly.
Use snprintf to avoid this. This was flagged during a Coverity scan
of the coreboot project, which also uses kconfig for its build system.
