Enable thread support and select thread implementation. With
glibc, thread support is mandatory but several
implementations are available. With uClibc, thread support
is optional, and when enabled, several implementations are
available. However, not all thread variants work with all
versions of uClibc for all architectures, the "linuxthreads
(stable/old)" may be a working fallback.
