In glibc 2.17, crypt() now expects 2 valid chars for the seed or
it will error out and return a NULL. The tinylogin code took the
result from crypt directly into a strcmp() which caused a segfault
Tinylogin has been deperacted, busybox now has login support, I will
investigate using busybox login support for 1.5.
