Uses abort() instead of raising a SIGABRT signal [-Werror]
error: ‘noreturn’ function does return [-Werror]
abort() is a noreturn function while raise() is not.
And because crypt_argchk() is flagged as __attribute__(noreturn), abort()
appears to be a better condidate.
This compilation warning has probably been introduced by commit
1809f741cba865b03d4db5c4ba8c41364a55d6bc.
