Hi Lianbo,

It seems that gdb cannot be built without gmp and mpfr. You can download 
the gmp and mpfr tarball and unpack them to the binutils-gdb source 
tree, rename gmp-<version>, mpfr-<version> to gmp, mpfr, then building 
gdb will also build the bundled gmp and mpfr, just like the gcc build 
system.
