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.

-      gdb can make use of the GMP and MPFR libraries.
-      
-      While the cross-gdb (above) can use the libraries compiled for the

-      eventually run).
-      
-      Setting this option will force building the GMP and MPFR libraries for
-      the target, and configure the native gdb to use them.
