busybox: PAM support needs thread support

Browse Source 
In commit f21b2558a0 ("busybox: added
linux-pam support"), we added optional support for PAM in
Busybox. However, this support requires the toolchain to have thread
support, which causes build failures with non-thread capable
toolchains.

This commit therefore enables Busybox PAM support only if the
linux-pam package is available *and the toolchain has thread support.

Fixes:
