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.
