That's a failure if toolchain is configured without threads.
This is what I see in config.log:

I was not able to reproduce that one and from build log I may assume
build process was terminated from outside ("ld terminated with signal 6
[Aborted]"). Is there a chance that build server was shut down or
something?

--------------------->8--------------------

This is because toolchain was built without threads and in case of
uClibc that lead to __UCLIBC_HAS_THREADS__ being undefined, which in
its turn undefines _POSIX_SEMAPHORES which is used in "empty.c":
--------------------->8--------------------
/* semaphores */
#ifdef _POSIX_SEMAPHORES
	#if defined(__linux__) && defined(__GNU_LIBRARY__) &&
!defined(_SEM_SEMUN_UNDEFINED)
		/* union semun is defined by including <sys/sem.h> */
	#else
		union semun {
			int val;
			struct semid_ds *buf;
		#ifdef __SVR4
			ushort_t	*array;
		#endif
		#ifdef __hpux__
			ushort		*array;
		#endif
		#ifdef __linux__
			unsigned short *array;
			struct seminfo *__buf;		/* buffer for
IPC_INFO */
		#endif
		};
  	#endif
#endif
	union semun semu;
--------------------->8--------------------

I'm not quite sure what's the correct solution here. Probably we may
just remove "#ifdef _POSIX_SEMAPHORES". That allowed me to compile that
package.

Any thoughts?

Looks like an issue in our tools, filed internal STAR 9000922620
against it.

But with mentioned patch I see another build failure:
--------------------->8--------------------

Known "cfi row mismatch [-Werror]". Will be fixed in RC2.
