When ldconfig hangs, it is in a mkstemp() call.  The mkstemp()
function probably uses random numbers to generate unique file names:

#0  0x8054340 in read ()
#1  0x804c966 in mktemp ()
#2  0x804ca33 in arc4random_stir ()
#3  0x804cad9 in arc4random ()
#4  0x804c791 in mktemp ()
#5  0x804c692 in mkstemp ()
#6  0x804886a in write_elf_hints ()
#7  0x8048818 in update_elf_hints ()
#8  0x8048c61 in main ()
#9  0x8048139 in _start ()
