 While I was checking the failing build logs, I see:
build/temp.linux-armv7l-2.7/scratch/tmp/timer_createOfMQXG.o: In
function `main':
timer_createOfMQXG.c:(.text+0x14): undefined reference to `timer_create'
collect2: error: ld returned 1 exit status

It's not just the implicit declaration, but a linker error later. I
can be wrong, but it seems it _may_ cause the test hang as there's no
timer to look for / to wait its expiration. Sorry if it happens in
normal logs as well; will check it tomorrow morning as it's almost
midnight here. :(
