binutils/binutils: companion libraries are not used

GNU binutils does not use the companion libraries, although
./configure advertises switches for them. This is because the
configure file is shared between different packages, and is
a bit 'lax' about what it checks. See:

     9 Hi,
    10 
    11 The appended patch fixes a typo in a low-level lock function.  It
    12 set the correct 3rd argument for the futex syscall in loop.  Sorry
    13 for missing such an embarrassing bug.
