libpam-otpw | undefined symbol: __aeabi_uidivmod

[qswks]

When trying to authenticate using otpw, the following error shows up in /var/log/auth.log

PAM unable to dlopen(pam_otpw.so): /lib/security/pam_otpw.so: undefined symbol: __aeabi_uidivmod

Same installation procedure in regular Debian (x86_64) works prefectly.

How to reproduce

• apt-get install libpam-otpw (1.3-2 in my case)
• Add a new file /etc/pam.d/otpw-auth with the following contents
  auth sufficient pam_otpw.so debug
session optional pam_otpw.so
• Modify /etc/pam.d/sshd, add a new entry @include otpw-auth just above @include common-auth.
• Enable ChallengeResponseAuthentication yes in /etc/ssh/sshd_config.
• Add AuthenticationMethods keyboard-interactive to etc/ssh/sshd_config (OpenSSH 6.2 or above required)

This isn't a linux (kernel) issue but a raspbian distribution issue.
