I don't know what symbol-server is, I can't help you with that.

To build gdb, you normally just need to run these commands at the
top-level:

  ./configure
  make all-gdb

The built gdb will be at gdb/gdb.  But there are some additional quirks
on macOS though, so it's not as simple as that.  GDB requires libgmp, so
you need to install that.  You need GNU make to build (the make that
comes with macOS is not GNU make).  You can install those using Macports
(or Brew, I guess) or by building them by hand.  You can then probably
get by using the commands:

  ./configure --disable-nls CFLAGS="-g3 -O0" CXXFLAGS="-std=gnu++17 -g3 -O0" --with-libgmp-prefix=/opt/local
  gmake

Update /opt/local to point where your libgmp is installed.  gmake refers
to GNU make, when installed through Macports.
