Masahiro Yamada 04dd61330f kconfig: fix infinite loop when expanding a macro at the end of file
[ 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: 104daea149c4 ("kconfig: reference environment variables directly and remove 'option env='")
