Starting with glibc-2.17, the crypt() function will report an EINVAL and return NULL when the format of the "salt" parameter is invalid. The current tests for crypt() pass its result to strcmp(), causing segfaults when the value returned from crypt() is NULL. This commit modifies the test programs to exit with failure when crypt() returns NULL. Reference: https://bugs.gentoo.org/show_bug.cgi?id=518964
