I'm not 100% sure I understand your question, but I assume you want to
cross-compile GDB on an x86-64 build machine, so that GDB runs and
debugs natively on a Microblaze Linux system.

At the simplest, it will be something like:

  .../configure --host=microblazeel-xilinx-linu-gnu --sysroot=<path to sysroot>
  make

But you will probably hit more problems that are typical of
cross-compilation (not specific to GDB), like making sure you have all
GDB dependencies built for Microblaze and installed in your sysroot.

GDB already supports Microblaze, see files gdb/microblaze* in the tree.
However, we didn't have contributions that touched those files for a
while, so it's possible these have bitrotted a little bit.
