	  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.
