commit: http://git.buildroot.net/buildroot/commit/?id=98e1848db11e707f96504ccf9cb2ed09e6787dd1
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/next

In commit f21b2558a097d07b53b6f20a47770468e9e4f7ed ("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:
