libpam uses libpthread, so for static builds busybox must be linked to
libpthread. On some platforms that requires an explicit -lpthread, so
it should be in LDLIBS. For non-static builds, scripts/trylink will
take care of removing -lpthread if possible. (Not bothering to check
CONFIG_STATIC because even in a non-static build it could be that the
only libpam available is libpam.a, so -lpthread could still be
needed.)
