You're building a gdb that runs on Android?  Or you want a GDBserver
that runs on Android, but debug from your x86_64 Ubuntu host?
If the latter, drop the --host part when building GDB, as you
want GDB that runs on x86_64.  You'll then need to build GDBserver
as a separate step, for an Android host, so you'll use the --host
setting then.  See:

So is "gcc" itself a native compiler running on Android?  If not,
then you should be seeing arm-linux-androideabi-gcc or some such here.
