debug/gdb: companion libs are not used

Although the gdb ./configure advertises for GMP and MPFR, those libraries
are not used by gdb (the ./configure is used across different packages,
hence the check for GMP/MPFR). See:
http://sourceware.org/ml/crossgcc/2010-08/msg00168.html

The same applies to MPC.

     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.

    14 

    15 Regards,
